The owner's manual says to charge the battery for at least 5 hours the
first time. The supplied battery is (1.6 * 1.2) or 1.9 watt-hours
nominal. If the five hours was a full charge, this implies that the
charger supplies at least 0.38 watt.

Go to Radio Shack and try their selection of Adaptaplugs until you find
the one that fits. If you don't mind spending what they charge for
adapters, buy a multi-output adapter and the Adaptaplug; otherwise tell
them you already have the adapter and buy just the Adaptaplug (which is
still a ripoff at $7). If you can solder, and the Adaptaplug happens to
be one of the sizes they carry in a "regular" plug (in the drawers full
of small parts), buy the "regular" plug instead; it's cheaper. If you
can solder and it's a weird size, just solder to the Adaptaplug pins
later. If you can't solder and it's a weird size, buy their 273-350
cable for $5, to turn the Adaptaplug ends into wires.
> What was the polarity of the tip and the ring?
Go home and plug the plug into the MP3 player. Use a multimeter to
measure the resistance between the negative battery contact and each pin
of the DC plug in turn. One pin will probably show a low, constant
resistance (less than 1 ohm.) This is the "negative" pin.
Now you need a somewhat discharged NiMH cell, some fresh alkaline cells
(AA size is fine, C or D will also work), tape (clear office type is
fine, but anything will work), and wire. Put the NiMH cell in the MP3
player. Tape a wire to the - side of one alkaline cell, and connect
that wire to the "negative" pin of the DC power plug. Connect another
wire to the "positive" pin of the DC power plug, and then touch it to
the + side of the alkaline cell. If the "charge" indicator on the MP3
player comes on and stays on, then you need a 1.5 V adapter.
If the "charge" indicator doesn't stay on, then use more tape and wire
to put a second alkaline cell in series with the first one, - to + .
Touch the wire from the DC power plug to the + side of the second
alkaline cell; if the "charge" indicator comes on and stays on, then
you need a 3 V adapter.
If you can't get any response by the time you get to 6 V (4 alkaline
cells in series), don't go up any further.
If you find a voltage that works, use the multimeter to measure the
current the MP3 player is drawing when charging the battery, and select
an adapter with a little more (not a lot more) current than that. Or,
divide 0.38 by the voltage you found to get an estimate - if you found
that 3 V worked, 0.38 W / 0.38 V = 0.13 A. Select an adapter with at
least the measured or estimated current, up to maybe twice the measured
or estimated current. A thrift store can be a good place to find an
adapter, if you don't mind shopping around a little.
Cut off the existing plug on the adapter (unless it happens to match)
and use the multimeter to figure out its polarity. Wire the adapter
to your new plug and enjoy.
Standard disclaimers apply: I don't get money or other consideration
from any companies mentioned.
Also, please be sure to wear appropriate personal protective equipment
while doing all this. You probably don't need arc flash protection at
this power level, but you do need gloves, safety goggles, hand rails,
and if your workspace is near the stairs, a properly-tethered fall
harness. Someone with first aid training needs to be nearby, and it
helps if there is an AED available. :)

I have several shoe boxes full of wall warts. It was a thrift store that came up with the computer cable with the odd Rio plug on one end. There are two thrift stores nearby with bins full of cheap, as in $1 or $2, wall warts. At yard sales, they usually fetch less than that. Finding one with the right current and the right voltage and the right polarity and the right size connector is the trick.
I've been thinking that 3 volts was about right.
Thanks for the help.

If this happened suddenly (one minute full deflection, the next half pix), it's most likely not a capacitor, at least not the only problem.
If it uses an IC for vertical deflection, it it most likely bad or can even have cracked solder along the pins. Try defluxing the pins thoroughly, then resolder with quality solder. If it runs OK, leave as is. Cracked solder is a function of age, heat, and vibration.
If the IC or discrete output transistors is\are bad, replace it and ESR every electrolytic in the circuit. A high ESR cap may not cause any initial symptom, but the IC will fail.

Actually, not in my experience. The boost cap or circuit only speeds up the retrace. What the OP described sounds like high ESR in the main output cap, if the unit has one. Because of the inductance of the yoke winding, high ESR acting like a resistor will cause the top of the raster to be still kinda stretched, but the bottom will be compressed because that is the part where it needs the low frequency component of the waveform. The boost cap only causes problems at the top usually.
I think the problem is going to be a large cap, like a 2,200 uF or so.

Good point. We do not know if the guy just got the thing or what. Almost any problem with the caps comes on gradually. It is quite rare that one goes all the sudden. If it does it is usually completely open or shorted, in either case there would probably be no deflection at all.
Actually a model number might help. I got two databases (paid) with a whole bunch of symcures. A print would be great. The thing might not even have an output coupling cap, which would mean the problem is likely the bottom output. (in IC or not)
On the other hand, the ramp cap associated with the vertical driver can also do that. Sometimes those are tantalum and they can fail just like that on occasion.

Yes. Now the argument can start. We can talk about whether it was the Christian Fundamentalists or the JEws who are at fault, or if there is no fault because the thing is 100 years old. Then we can go into the Prussian governemnt's involvment in the current middle east crisis.
But let's not forget about the Russians and their hand in not stopping the tragedy of 9/11 which killed almost as many people as hospitals and drunk drivers combined in a month.
Then there are those socio-economic factors that make most of us not give a fuck anymore.
Or we can start picking on Phil Allison. Your call.

I have from year two thousand written numerous short stories and compendia for the business world. However, I have not yet published a completely finished book despite the fact that it is ready for a final editing and publishing on a software for e-books on the internet. It was a time when I learned how to in a standard set up a writing on a completely finished template into a complete book. The great thing about this software that I use to write my memoirs with is absolutely stunning in that it automatically sets up the text and create a book form each capital for itself. I started using the downloaded software toolbar to go through the entire structure of the book, and it's done in a few hours. But it takes a lot more than just a piece of software to get started with the writing. And this I speak based on my own experience of being a writer full time. I have bridged a knowledge gap that otherwise is so unusual or hardly even occurred in a context of eroticism and loveware.
The comprehensive steps to complete mastery of a writing style are available to all, and there is an endless bunch of different ways to get your own style. Knowledge source using the constituting factor for a decision to be a writer was for me poetry and the study of poetry. I also have a technological academic background and not a literary academic background, I would say. With a very limited literary academic knowledge so I can still today produce a very distinctive writing style which is also my signature and a living language for a reader. I would also like to add that for me personally this level of writing is an extremely large and solid knowledge in itself. With the insight and feedback, I am completely convinced that this level that I am talking about and have chosen to work with, it is by far the best-selling author's style in literature and in the bookstore. If I rather chose a stilted language and a professional editor, what do you think that the feeling of a story had been? In addition, the jargon in high yield use of language is always more formidable with communication while a fiction is more of a feeling and to express emotions.
According to my models in art creation so we find, among other things, a professor from Yale University named Robert j. Schiller. There is also another person who has been incredibly inspirational for me in this work and it is a writer and former principal at a high school in London. She has also contributed with a workshop online where she with her incredible enthusiasm, describes the framework for the structure of a writing career.
Is there anyone willing to write some review and publish it to this resource that I am providing in the write of Intimate and romantic fiction? I am thinking about soon get into the write and sell my produced fiction stories. However, I am very limited today for the spreed of this sort of production because search engines are set restrictive to list my web pages even though it is not aggressive Indecency on the internet but on the contrary as it is about beautiful Intimate and romantic write that is otherwise so extremely popular among some of my fellow writers. Se the web page here and forward it online so that as many as can find this resource, if you like! http://www.mixet.se/romance.html

I have a 1970's GE clock transistor radio. On AM stations, (1060) there is a lot of buzz/hum. However when I turn ON various CFL light fixtures around the house, the hum disappears. Is there a filter commercially available to put on the AC line? Or can I make one? I've tried reversing the plug (that used to work years ago). Any suggestions?

And, get OE Fix, too. :-)
In all fairness to Phil, after he had his grumpy juice for
breakfast, he did state to put the capacitor across the
incoming AC line i.e. parallel. With a molded plug you would
have to be quite clever, but you may buy a replacement, two
piece plug and wire the capacitor into the circuit, minding
to heat shrink the capacitor leads.

Forget it, none of this shit is going to work. The simple fact is that there is so much shit putting out interference in that band that nothing is going to eliminate it.
You can't shield it from the power line because it is conming in from THE ANTENNA ! You would have to filter the frequencies you want to recieve.
It's different when you are out in a truck on the highway in bumfuct Kansas somewhere. Then AM can work.
Think about it, AM is about one megacycle. Yup, not even Hertz. It's that old. I hate to say it, but AM is just about dead. I used to like CKLW. In fact CKLW used to be one of the most popular stations in the whole country. The problem now is that even your fucking clothes apparently enamate RF in that low band.
Shortwave is just as bad.
There is a damn good reason that the technology has tended toward higher frequencies. In fact, like OVER ten years ago I advocated the elimnination of the VHF band for television. On channel 3 (US, about 60 Mhz) if a car was driving down the road and had a bad spark plug wire it would cause interference.

You seem to be retarded. The OP already stated that the noise was eliminated by
turning on a CFL.
If the OP could kill the power to the receptacle, solder some extension wire to the
cap leads, and then wire the cap across the back of the receptacle. Minding to heat
shrink the leads of the cap, and using a larger heat shrink, encapsulate the cap and
all of the smaller heat shrink. Make the extension leads 6" long.

Wouldn't it be easier to put the cap inside the radio?
Be careful with your choice of cap.
I put a quality 600V cap across 220VAC inside the dryer to
bridge the phases to make X10 work. Worked great for two
years before it exploded spectacularly. Good thing it was
inside a metal box.

Forget it, none of this shit is going to work.
** So you do not understand the issue.
AM radio often signals "piggy back" into premises on the AC power and are
then re- radiated with supply frequency related modulation - mainly 100
or 120Hz and harmonics.
They also arrive by penetrating walls and windows without such modulation.
The loopstick antenna in the OP's radio picks up either or both.
It may even have a small cap connecting to the incoming AC to enhance the
effect.
Get it now?

** My post specified a 275VAC cap ( aka class X1 or X2 suppression caps) .
These are specially would to avoid internal corona that destroys ordinary
film caps wired across the AC line.
If you cannot get any, try two 600V film caps in series - that ought to
work OK too.

I was looking on badcaps.net and someone said they "After replacing those stressed 'lytics," - your Panasonic model - all the high Voltage primaries - it still didn't work. But those weren't the bad caps. I've only seen ONE switching power supply that lost a high Voltage cap. The vast majority are in the control loop and the output caps. Often they are bulging but not always. If they ARE bulging they need to go. I've seen no surface mount caps that bulged but LOTS (LOTS!!) of bad ones. They are THE WORST for failing but are some of the easiest to replace. I use a cutter with a very thin nose and cut them out. Do NOT cut at the bottom as you'll tear off the pads. Cut the cap at the seal crimp point and then remove the seal disc. Then clip off the wide part of the leads, remove the plastic base and un-solder the old flat leads.

We bought the TV from Best Buy. Extended warranty expired 1.5 years ago. From what I found online, the A board is bad. This is where the input wires plug into. I'm not sure where to buy it from without getting ripped off. Can someone point me in the right direction please? Geek squad price is $350 for the part plus $150 labor.
Also a way to look up the part number and price of the part would be a huge help.
Thanks! Rich

Ok I'll bite. "No one" wouldn't neccessarily include those where
English is their second language.
My "background" is an electromechanical Journeyman / Apprenticeship
- not sure what the English equivalent is.
I have owned a variety of test gear, including a scope.
I have fixed or *modified* dozens of VCRs (Beta, SVHS, Hi8), the odd
TV, lots of communication-types of radios, and done some minor surface
component work.
Time is valuable -- particularly when TVs are not your specialty,
so just trying to get some ideas from those who deal with that sort of
thing on a regular basis.
No offence taken though, Phil, you provide a lot of valuable input
otherwise.

Check the vertical deflection driver if new caps (use good quality 105C
ones of course!) don't fix the problem.
Use low ESR caps for anything on the horizontal circuit, check the other
electrolytic caps using an ESR meter like the blue Bob Robert ESR meter
kit one that we sell.
We've also replaced a lot of the associated deflection transistors in
vertical circuits when the cap failed...

My experience with CRT type tv's and monitors over the past 40 years has been about 75% of the time bad electrolytic capacitors have been the cause of problems. The other 25% of the time it has been solid state components like transistors, IC's, diodes, etc causing troubles.
In your case I think the first place to look is at any electrolytic capacitors in the vertical deflection stage. There might be an obvious bad one with a bulged/blown out top or leaking out the bottom of it. Naturally, a capacitor meter would be a big help in testing the capacitors and finding an electrically bad one.
The vertical output stage may either have a pair of transistors (one operates the top half of the picture and the other operates the bottom half) running it or it could have the vertical output stage combined in a single integrated circuit which is usually bolted to a heat sink to keep it cool.

Forgot to mention, likely capacitors causing your problem could be ones either rated at 1000 to 2200 uf (around 10 to 25 volts) or look for any that are rated at a small uf like 3.3 uf but at higher voltage like say for instance 160 volts.
I had one of those Harbor Freight 5" B&W security camera monitors with a "no vertical deflection" symptom and it turned out to have two bad electrolytic capacitors: a 2200 uf @ 10 volts and a 3.3 uf @ 160 volts. Replacing them restored the monitor back to full operation again.

My experience - boost capacitor, often about 100uF at 35 volts, near the
vertical output IC.

If this happened suddenly (one minute full deflection, the next half pix), it's most likely not a capacitor, at least not the only problem.
If it uses an IC for vertical deflection, it it most likely bad or can even have cracked solder along the pins. Try defluxing the pins thoroughly, then resolder with quality solder. If it runs OK, leave as is. Cracked solder is a function of age, heat, and vibration.
If the IC or discrete output transistors is\are bad, replace it and ESR every electrolytic in the circuit. A high ESR cap may not cause any initial symptom, but the IC will fail.

Actually, not in my experience. The boost cap or circuit only speeds up the retrace. What the OP described sounds like high ESR in the main output cap, if the unit has one. Because of the inductance of the yoke winding, high ESR acting like a resistor will cause the top of the raster to be still kinda stretched, but the bottom will be compressed because that is the part where it needs the low frequency component of the waveform. The boost cap only causes problems at the top usually.
I think the problem is going to be a large cap, like a 2,200 uF or so.

Good point. We do not know if the guy just got the thing or what. Almost any problem with the caps comes on gradually. It is quite rare that one goes all the sudden. If it does it is usually completely open or shorted, in either case there would probably be no deflection at all.
Actually a model number might help. I got two databases (paid) with a whole bunch of symcures. A print would be great. The thing might not even have an output coupling cap, which would mean the problem is likely the bottom output. (in IC or not)
On the other hand, the ramp cap associated with the vertical driver can also do that. Sometimes those are tantalum and they can fail just like that on occasion.

Yes. Now the argument can start. We can talk about whether it was the Christian Fundamentalists or the JEws who are at fault, or if there is no fault because the thing is 100 years old. Then we can go into the Prussian governemnt's involvment in the current middle east crisis.
But let's not forget about the Russians and their hand in not stopping the tragedy of 9/11 which killed almost as many people as hospitals and drunk drivers combined in a month.
Then there are those socio-economic factors that make most of us not give a fuck anymore.
Or we can start picking on Phil Allison. Your call.

Hi. The RioS50 mp3 player was on the market some ten years ago. The owner's manual and reviews are easily found online. I got one at a yard sale for not much money a few years back. It lacked the charger and the cable that allows one to download songs from a computer. "That's why it's so cheap," the seller said.
Almost incredibly, I found the cable at a thrift store. iTunes recognizes the device, and it works with Rio's software as well. Storage is limited, but it has an FM radio. It still works, and I still use it.
It was designed to run off a 1600 mAh NiMH cell. It can run off an alkaline cell or a NiCd cell too. Because I do not have the charger, I have to remove any rechargeable cell for recharging. Although the owner's manual and reviews are online, I have not found the details for the recharger. What was its output voltage? How much current did it supply? What was the size of the barrel connector? What was the polarity of the tip and the ring?
If anyone can come up with that information, I would be grateful. The charger probably worked with other Rio players that ran off a single 1.25 volt or 1.50 volt cell.
Thank you.

Probably more than 1.2 V. More below.
> How much current did it supply?
The owner's manual says to charge the battery for at least 5 hours the
first time. The supplied battery is (1.6 * 1.2) or 1.9 watt-hours
nominal. If the five hours was a full charge, this implies that the
charger supplies at least 0.38 watt.
> What was the size of the barrel connector?
Go to Radio Shack and try their selection of Adaptaplugs until you find
the one that fits. If you don't mind spending what they charge for
adapters, buy a multi-output adapter and the Adaptaplug; otherwise tell
them you already have the adapter and buy just the Adaptaplug (which is
still a ripoff at $7). If you can solder, and the Adaptaplug happens to
be one of the sizes they carry in a "regular" plug (in the drawers full
of small parts), buy the "regular" plug instead; it's cheaper. If you
can solder and it's a weird size, just solder to the Adaptaplug pins
later. If you can't solder and it's a weird size, buy their 273-350
cable for $5, to turn the Adaptaplug ends into wires.
> What was the polarity of the tip and the ring?
Go home and plug the plug into the MP3 player. Use a multimeter to
measure the resistance between the negative battery contact and each pin
of the DC plug in turn. One pin will probably show a low, constant
resistance (less than 1 ohm.) This is the "negative" pin.
Now you need a somewhat discharged NiMH cell, some fresh alkaline cells
(AA size is fine, C or D will also work), tape (clear office type is
fine, but anything will work), and wire. Put the NiMH cell in the MP3
player. Tape a wire to the - side of one alkaline cell, and connect
that wire to the "negative" pin of the DC power plug. Connect another
wire to the "positive" pin of the DC power plug, and then touch it to
the + side of the alkaline cell. If the "charge" indicator on the MP3
player comes on and stays on, then you need a 1.5 V adapter.
If the "charge" indicator doesn't stay on, then use more tape and wire
to put a second alkaline cell in series with the first one, - to + .
Touch the wire from the DC power plug to the + side of the second
alkaline cell; if the "charge" indicator comes on and stays on, then
you need a 3 V adapter.
If you can't get any response by the time you get to 6 V (4 alkaline
cells in series), don't go up any further.
If you find a voltage that works, use the multimeter to measure the
current the MP3 player is drawing when charging the battery, and select
an adapter with a little more (not a lot more) current than that. Or,
divide 0.38 by the voltage you found to get an estimate - if you found
that 3 V worked, 0.38 W / 0.38 V = 0.13 A. Select an adapter with at
least the measured or estimated current, up to maybe twice the measured
or estimated current. A thrift store can be a good place to find an
adapter, if you don't mind shopping around a little.
Cut off the existing plug on the adapter (unless it happens to match)
and use the multimeter to figure out its polarity. Wire the adapter
to your new plug and enjoy.
Standard disclaimers apply: I don't get money or other consideration
from any companies mentioned.
Also, please be sure to wear appropriate personal protective equipment
while doing all this. You probably don't need arc flash protection at
this power level, but you do need gloves, safety goggles, hand rails,
and if your workspace is near the stairs, a properly-tethered fall
harness. Someone with first aid training needs to be nearby, and it
helps if there is an AED available. :)

I have several shoe boxes full of wall warts. It was a thrift store that came up with the computer cable with the odd Rio plug on one end. There are two thrift stores nearby with bins full of cheap, as in $1 or $2, wall warts. At yard sales, they usually fetch less than that. Finding one with the right current and the right voltage and the right polarity and the right size connector is the trick.
I've been thinking that 3 volts was about right.

I have from year two thousand written numerous short stories and compendia for the business world. However, I have not yet published a completely finished book despite the fact that it is ready for a final editing and publishing on a software for e-books on the internet. It was a time when I learned how to in a standard set up a writing on a completely finished template into a complete book. The great thing about this software that I use to write my memoirs with is absolutely stunning in that it automatically sets up the text and create a book form each capital for itself. I started using the downloaded software toolbar to go through the entire structure of the book, and it's done in a few hours. But it takes a lot more than just a piece of software to get started with the writing. And this I speak based on my own experience of being a writer full time. I have bridged a knowledge gap that otherwise is so unusual or hardly even occurred in a context of eroticism and loveware.
The comprehensive steps to complete mastery of a writing style are available to all, and there is an endless bunch of different ways to get your own style. Knowledge source using the constituting factor for a decision to be a writer was for me poetry and the study of poetry. I also have a technological academic background and not a literary academic background, I would say. With a very limited literary academic knowledge so I can still today produce a very distinctive writing style which is also my signature and a living language for a reader. I would also like to add that for me personally this level of writing is an extremely large and solid knowledge in itself. With the insight and feedback, I am completely convinced that this level that I am talking about and have chosen to work with, it is by far the best-selling author's style in literature and in the bookstore. If I rather chose a stilted language and a professional editor, what do you think that the feeling of a story had been? In addition, the jargon in high yield use of language is always more formidable with communication while a fiction is more of a feeling and to express emotions.
According to my models in art creation so we find, among other things, a professor from Yale University named Robert j. Schiller. There is also another person who has been incredibly inspirational for me in this work and it is a writer and former principal at a high school in London. She has also contributed with a workshop online where she with her incredible enthusiasm, describes the framework for the structure of a writing career.
Is there anyone willing to write some review and publish it to this resource that I am providing in the write of Intimate and romantic fiction? I am thinking about soon get into the write and sell my produced fiction stories. However, I am very limited today for the spreed of this sort of production because search engines are set restrictive to list my web pages even though it is not aggressive Indecency on the internet but on the contrary as it is about beautiful Intimate and romantic write that is otherwise so extremely popular among some of my fellow writers. Se the web page here and forward it online so that as many as can find this resource, if you like! http://www.mixet.se/romance.html

In all fairness to Phil, after he had his grumpy juice for
breakfast, he did state to put the capacitor across the
incoming AC line i.e. parallel. With a molded plug you would
have to be quite clever, but you may buy a replacement, two
piece plug and wire the capacitor into the circuit, minding
to heat shrink the capacitor leads.

Forget it, none of this shit is going to work. The simple fact is that there is so much shit putting out interference in that band that nothing is going to eliminate it.
You can't shield it from the power line because it is conming in from THE ANTENNA ! You would have to filter the frequencies you want to recieve.
It's different when you are out in a truck on the highway in bumfuct Kansas somewhere. Then AM can work.
Think about it, AM is about one megacycle. Yup, not even Hertz. It's that old. I hate to say it, but AM is just about dead. I used to like CKLW. In fact CKLW used to be one of the most popular stations in the whole country. The problem now is that even your fucking clothes apparently enamate RF in that low band.
Shortwave is just as bad.
There is a damn good reason that the technology has tended toward higher frequencies. In fact, like OVER ten years ago I advocated the elimnination of the VHF band for television. On channel 3 (US, about 60 Mhz) if a car was driving down the road and had a bad spark plug wire it would cause interference.
Fuck that.

You seem to be retarded. The OP already stated that the noise was eliminated by
turning on a CFL.
If the OP could kill the power to the receptacle, solder some extension wire to the
cap leads, and then wire the cap across the back of the receptacle. Minding to heat
shrink the leads of the cap, and using a larger heat shrink, encapsulate the cap and
all of the smaller heat shrink. Make the extension leads 6" long.

Ok I'll bite. "No one" wouldn't neccessarily include those where
English is their second language.
My "background" is an electromechanical Journeyman / Apprenticeship
- not sure what the English equivalent is.
I have owned a variety of test gear, including a scope.
I have fixed or *modified* dozens of VCRs (Beta, SVHS, Hi8), the odd
TV, lots of communication-types of radios, and done some minor surface
component work.
Time is valuable -- particularly when TVs are not your specialty,
so just trying to get some ideas from those who deal with that sort of
thing on a regular basis.
No offence taken though, Phil, you provide a lot of valuable input

Check the vertical deflection driver if new caps (use good quality 105C
ones of course!) don't fix the problem.
Use low ESR caps for anything on the horizontal circuit, check the other
electrolytic caps using an ESR meter like the blue Bob Robert ESR meter
kit one that we sell.
We've also replaced a lot of the associated deflection transistors in
vertical circuits when the cap failed...

My experience with CRT type tv's and monitors over the past 40 years has been about 75% of the time bad electrolytic capacitors have been the cause of problems. The other 25% of the time it has been solid state components like transistors, IC's, diodes, etc causing troubles.
In your case I think the first place to look is at any electrolytic capacitors in the vertical deflection stage. There might be an obvious bad one with a bulged/blown out top or leaking out the bottom of it. Naturally, a capacitor meter would be a big help in testing the capacitors and finding an electrically bad one.
The vertical output stage may either have a pair of transistors (one operates the top half of the picture and the other operates the bottom half) running it or it could have the vertical output stage combined in a single integrated circuit which is usually bolted to a heat sink to keep it cool.

Forgot to mention, likely capacitors causing your problem could be ones either rated at 1000 to 2200 uf (around 10 to 25 volts) or look for any that are rated at a small uf like 3.3 uf but at higher voltage like say for instance 160 volts.
I had one of those Harbor Freight 5" B&W security camera monitors with a "no vertical deflection" symptom and it turned out to have two bad electrolytic capacitors: a 2200 uf @ 10 volts and a 3.3 uf @ 160 volts. Replacing them restored the monitor back to full operation again.

If this happened suddenly (one minute full deflection, the next half pix), it's most likely not a capacitor, at least not the only problem.
If it uses an IC for vertical deflection, it it most likely bad or can even have cracked solder along the pins. Try defluxing the pins thoroughly, then resolder with quality solder. If it runs OK, leave as is. Cracked solder is a function of age, heat, and vibration.
If the IC or discrete output transistors is\are bad, replace it and ESR every electrolytic in the circuit. A high ESR cap may not cause any initial symptom, but the IC will fail.

Actually, not in my experience. The boost cap or circuit only speeds up the retrace. What the OP described sounds like high ESR in the main output cap, if the unit has one. Because of the inductance of the yoke winding, high ESR acting like a resistor will cause the top of the raster to be still kinda stretched, but the bottom will be compressed because that is the part where it needs the low frequency component of the waveform. The boost cap only causes problems at the top usually.
I think the problem is going to be a large cap, like a 2,200 uF or so.

Good point. We do not know if the guy just got the thing or what. Almost any problem with the caps comes on gradually. It is quite rare that one goes all the sudden. If it does it is usually completely open or shorted, in either case there would probably be no deflection at all.
Actually a model number might help. I got two databases (paid) with a whole bunch of symcures. A print would be great. The thing might not even have an output coupling cap, which would mean the problem is likely the bottom output. (in IC or not)
On the other hand, the ramp cap associated with the vertical driver can also do that. Sometimes those are tantalum and they can fail just like that on occasion.

Yes. Now the argument can start. We can talk about whether it was the Christian Fundamentalists or the JEws who are at fault, or if there is no fault because the thing is 100 years old. Then we can go into the Prussian governemnt's involvment in the current middle east crisis.
But let's not forget about the Russians and their hand in not stopping the tragedy of 9/11 which killed almost as many people as hospitals and drunk drivers combined in a month.
Then there are those socio-economic factors that make most of us not give a fuck anymore.

Hi. The RioS50 mp3 player was on the market some ten years ago. The owner's manual and reviews are easily found online. I got one at a yard sale for not much money a few years back. It lacked the charger and the cable that allows one to download songs from a computer. "That's why it's so cheap," the seller said.
Almost incredibly, I found the cable at a thrift store. iTunes recognizes the device, and it works with Rio's software as well. Storage is limited, but it has an FM radio. It still works, and I still use it.
It was designed to run off a 1600 mAh NiMH cell. It can run off an alkaline cell or a NiCd cell too. Because I do not have the charger, I have to remove any rechargeable cell for recharging. Although the owner's manual and reviews are online, I have not found the details for the recharger. What was its output voltage? How much current did it supply? What was the size of the barrel connector? What was the polarity of the tip and the ring?
If anyone can come up with that information, I would be grateful. The charger probably worked with other Rio players that ran off a single 1.25 volt or 1.50 volt cell.
Thank you.

> How much current did it supply?
The owner's manual says to charge the battery for at least 5 hours the
first time. The supplied battery is (1.6 * 1.2) or 1.9 watt-hours
nominal. If the five hours was a full charge, this implies that the
charger supplies at least 0.38 watt.
> What was the size of the barrel connector?
Go to Radio Shack and try their selection of Adaptaplugs until you find
the one that fits. If you don't mind spending what they charge for
adapters, buy a multi-output adapter and the Adaptaplug; otherwise tell
them you already have the adapter and buy just the Adaptaplug (which is
still a ripoff at $7). If you can solder, and the Adaptaplug happens to
be one of the sizes they carry in a "regular" plug (in the drawers full
of small parts), buy the "regular" plug instead; it's cheaper. If you
can solder and it's a weird size, just solder to the Adaptaplug pins
later. If you can't solder and it's a weird size, buy their 273-350
cable for $5, to turn the Adaptaplug ends into wires.
> What was the polarity of the tip and the ring?
Go home and plug the plug into the MP3 player. Use a multimeter to
measure the resistance between the negative battery contact and each pin
of the DC plug in turn. One pin will probably show a low, constant
resistance (less than 1 ohm.) This is the "negative" pin.
Now you need a somewhat discharged NiMH cell, some fresh alkaline cells
(AA size is fine, C or D will also work), tape (clear office type is
fine, but anything will work), and wire. Put the NiMH cell in the MP3
player. Tape a wire to the - side of one alkaline cell, and connect
that wire to the "negative" pin of the DC power plug. Connect another
wire to the "positive" pin of the DC power plug, and then touch it to
the + side of the alkaline cell. If the "charge" indicator on the MP3
player comes on and stays on, then you need a 1.5 V adapter.
If the "charge" indicator doesn't stay on, then use more tape and wire
to put a second alkaline cell in series with the first one, - to + .
Touch the wire from the DC power plug to the + side of the second
alkaline cell; if the "charge" indicator comes on and stays on, then
you need a 3 V adapter.
If you can't get any response by the time you get to 6 V (4 alkaline
cells in series), don't go up any further.
If you find a voltage that works, use the multimeter to measure the
current the MP3 player is drawing when charging the battery, and select
an adapter with a little more (not a lot more) current than that. Or,
divide 0.38 by the voltage you found to get an estimate - if you found
that 3 V worked, 0.38 W / 0.38 V = 0.13 A. Select an adapter with at
least the measured or estimated current, up to maybe twice the measured
or estimated current. A thrift store can be a good place to find an
adapter, if you don't mind shopping around a little.
Cut off the existing plug on the adapter (unless it happens to match)
and use the multimeter to figure out its polarity. Wire the adapter
to your new plug and enjoy.
Standard disclaimers apply: I don't get money or other consideration
from any companies mentioned.
Also, please be sure to wear appropriate personal protective equipment
while doing all this. You probably don't need arc flash protection at
this power level, but you do need gloves, safety goggles, hand rails,
and if your workspace is near the stairs, a properly-tethered fall
harness. Someone with first aid training needs to be nearby, and it
helps if there is an AED available. :)

I have several shoe boxes full of wall warts. It was a thrift store that came up with the computer cable with the odd Rio plug on one end. There are two thrift stores nearby with bins full of cheap, as in $1 or $2, wall warts. At yard sales, they usually fetch less than that. Finding one with the right current and the right voltage and the right polarity and the right size connector is the trick.

I have from year two thousand written numerous short stories and compendia for the business world. However, I have not yet published a completely finished book despite the fact that it is ready for a final editing and publishing on a software for e-books on the internet. It was a time when I learned how to in a standard set up a writing on a completely finished template into a complete book. The great thing about this software that I use to write my memoirs with is absolutely stunning in that it automatically sets up the text and create a book form each capital for itself. I started using the downloaded software toolbar to go through the entire structure of the book, and it's done in a few hours. But it takes a lot more than just a piece of software to get started with the writing. And this I speak based on my own experience of being a writer full time. I have bridged a knowledge gap that otherwise is so unusual or hardly even occurred in a context of eroticism and loveware.
The comprehensive steps to complete mastery of a writing style are available to all, and there is an endless bunch of different ways to get your own style. Knowledge source using the constituting factor for a decision to be a writer was for me poetry and the study of poetry. I also have a technological academic background and not a literary academic background, I would say. With a very limited literary academic knowledge so I can still today produce a very distinctive writing style which is also my signature and a living language for a reader. I would also like to add that for me personally this level of writing is an extremely large and solid knowledge in itself. With the insight and feedback, I am completely convinced that this level that I am talking about and have chosen to work with, it is by far the best-selling author's style in literature and in the bookstore. If I rather chose a stilted language and a professional editor, what do you think that the feeling of a story had been? In addition, the jargon in high yield use of language is always more formidable with communication while a fiction is more of a feeling and to express emotions.
According to my models in art creation so we find, among other things, a professor from Yale University named Robert j. Schiller. There is also another person who has been incredibly inspirational for me in this work and it is a writer and former principal at a high school in London. She has also contributed with a workshop online where she with her incredible enthusiasm, describes the framework for the structure of a writing career.
Is there anyone willing to write some review and publish it to this resource that I am providing in the write of Intimate and romantic fiction? I am thinking about soon get into the write and sell my produced fiction stories. However, I am very limited today for the spreed of this sort of production because search engines are set restrictive to list my web pages even though it is not aggressive Indecency on the internet but on the contrary as it is about beautiful Intimate and romantic write that is otherwise so extremely popular among some of my fellow writers. Se the web page here and forward it online so that as many as can find this resource, if you like! http://www.mixet.se/romance.html

Thnks Phil. does that cap go in series with one lead of an ACPlug, or across thepower line.

In all fairness to Phil, after he had his grumpy juice for
breakfast, he did state to put the capacitor across the
incoming AC line i.e. parallel. With a molded plug you would
have to be quite clever, but you may buy a replacement, two
piece plug and wire the capacitor into the circuit, minding
to heat shrink the capacitor leads.

Forget it, none of this shit is going to work. The simple fact is that there is so much shit putting out interference in that band that nothing is going to eliminate it.
You can't shield it from the power line because it is conming in from THE ANTENNA ! You would have to filter the frequencies you want to recieve.
It's different when you are out in a truck on the highway in bumfuct Kansas somewhere. Then AM can work.
Think about it, AM is about one megacycle. Yup, not even Hertz. It's that old. I hate to say it, but AM is just about dead. I used to like CKLW. In fact CKLW used to be one of the most popular stations in the whole country. The problem now is that even your fucking clothes apparently enamate RF in that low band.
Shortwave is just as bad.
There is a damn good reason that the technology has tended toward higher frequencies. In fact, like OVER ten years ago I advocated the elimnination of the VHF band for television. On channel 3 (US, about 60 Mhz) if a car was driving down the road and had a bad spark plug wire it would cause interference.
Fuck that.

You seem to be retarded. The OP already stated that the noise was eliminated by
turning on a CFL.
If the OP could kill the power to the receptacle, solder some extension wire to the
cap leads, and then wire the cap across the back of the receptacle. Minding to heat
shrink the leads of the cap, and using a larger heat shrink, encapsulate the cap and
all of the smaller heat shrink. Make the extension leads 6" long.

Well I've never paid $200 for Windows, and I use a firewall. *IF* all the
software I choose to use was available for Linux, AND all the drivers were
available for the hardware I choose to use, I'd happily run Linux on my
computers. Been waiting for a couple of decades for that to happen, and not
holding my breathe though.

The Apple ipod itunes crap is the only problem, Windows works well with
every other MP3 player that I've ever used. But so does Linux for that
matter.

In the days when computing power was far more limited than it is now, it was
a neccessity. But since I've had no problems doing all my multi-track audio
work on generic computers for the last decade, I'm not in a hurry to go down
the expensive, locked in, hope they might give you what you want/need
someday path ever again. Because so many others agree is why those systems
no longer sell.
Some people might want a brand new Nagra tape machine too, but not enough to
make it a commercially viable business plan it seems.

The "throw more CPU power at it and hope it works" philosophy works fine
as long as there's plenty of CPU power for what you want to do. But how
long is that going to continue?

Dunno, Nagra seems to be doing pretty well right now. They don't sell a lot
of analogue machines, but they're not out of the catalogue yet.

Dead right. I'm not only amused but annoyed they find it necessary to mess
with the desktop interface every time they bring out an update, when all I
want is the fastest way to get to the applications (with support for all the
new hardware technolgy since the last release).
Windows 8 sure aint it IMO :-(

See, I would consider Solaris a lot more advanced, in terms of actually having
a solid kernel that has been well-debugged and is stable. Turn off the stupid
java gui and all that crap and you have a very solid OS that does not require
constant patching.
My complaint with Linux is mostly that the Linux community is constantly
changing things, and they often don't change them for the better or the
worse, they just change them for the sake of changing them. This seems like
misplaced effort on the part of developers, but what bothers me is that now
I have to change my stuff unnecessarily.
I would much prefer a system that was actually designed, where someone sat
down and made a decision about what the thing was supposed to do and then
built it to do that and then removed bugs rather than added features.
But... when systems are built like that, they aren't systems for everything,
they are systems for the one thing the designer decided it was supposed to
do. And if that's not what you want... that should be fine because there
should be plenty of other systems out there to do other things.
It's the lack of those other systems that I am bemoaning.

Every week someone finds some security vulnerability that needs to get
patched. Every week someone makes some unneeded change. If there is a
problem with a third-party device driver I can't call up DEC support
on a three-way call and have the DEC developers working with the third-party
guys to fix the problem.

No, you don't just write drivers. If you want an actual hard realtime
system you either need to wrest control away from the OS and do everything
as one uninterruptable process, or you need an operating system with a
scheduler that assigns timeslices to processes based upon how much time
those processes need to make deadline. When you make a call to the operating
system, say open(), one of the parameters is how long you have to wait for
the OS to do the job, and the kernel will prioritize the call appropriately
to make sure all those calls return in time.
The alternative is just to throw CPU at the problem and hope everybody can
meet deadline. This is called "soft realtime" and sometimes it works and
sometimes it doesn't. What is evil is that sometimes it's not always obvious
at the time that data is being lost because there is no way for the kernel
or the application to flag that it's missing deadlines in many cases.

Exactly, I specifically said "*tape* machine". Where are the new models?
Can't justify the development costs would be my guess.

Seems to be increasing true wrt audio, given the continued rate of increase
in CPU horsepower and RAM size versus software requirement on it. Even
CPU-hungry plugins don't seem to be the problem they used to be.
This applies to everything I've ever done, except for video-rendering which
is and probably always will be ever-expanding in the resource demand dept

Chicken-egg thing really. Features need to be added because of commercial
really - other products may sport such features (sometimes even good and
truely useful ones !) , and 'whatever' OS needs to keep it's user base to
survive.

The general ... Leviathan nature of mass market computing means people
will adapt the general to the specific, because it costs much less than
designing for specific from the git-go.
And frankly, it's not something I'd consider a very real problem at
this writing. I can run a DAW in a VM at times ( because the VM is 32
bit ) and nary a glitch.

With apologies to Edgar Allen Poe...
Once upon a Tuesday dreary, while I pondered, weak and weary,
Installing the same version of Windows once more.
While I cursed the constant crashing, I made a fist and started bashing,
Started bashing the computer case and CD-ROM drive door.
"Piece of crap," I muttered, bashing the CD-ROM drive door,
"I will take this crap no more!"
Distinctly I do remember, when I bought my PC in December,
The marketing man said this software would crash no more.
Eagerly I wished to borrow a tool to inflict pain and sorrow
So that one day, perhaps tomorrow, I could go to my computer store
For the chance to make the salesman sell this crap no more.
Only this and nothing more.
So after wasting countless hours, I unplugged the beige mini-tower.
My day was looking very tragic like the old poetry of gothic lore,
But suddenly there came a tapping, rhymthic like the beats of rapping.
Actually, it sounded like flippers flapping, flapping at my apartment door.
"That is very odd," I muttered, "the time is nearly half past four,
Who is knocking on my door?"
The door was opened but it only revealed a penguin standing quite lonely,
Standing with a bag of CD-ROMs on the stoop before my apartment door.
I thought at first it was a delusion, for I was wrought with great confusion
Over the presence of a flightless Antarctic bird at my apartment door.
So I stood there, looking quite the fool, with my jaw down to the floor.
Then the bird said, "Pay no more!"
I thought to call the SPCA ... perhaps it escaped the zoo today.
But instead I brought the talking Aptenodytes forsteri inside my door.
He looked around, he looked at me ... and then he waddled to my PC.
I followed fast and I did see him place his disc in my drive door.
His program booted and began to install software I'd never seen before,
Then the bird said, "Pay No More!"
He brought me LINUX to install, said it rarely crashed at all.
Then he showed me some books while the software installed some more.
The interface, it looked like UNIX ... but 'twas much cheaper than QNX.
In fact, the code was open, so the source of bugs was hidden no more

I've been using Windows since 3.0. That version tended to crash for no obvious
reason. I've not had that problem with any later version.
Around 2004, "something" went wrong with my Windows 2000 installation. It
would boot, but its behavior was screwy. (This might have been due to a
malware attack, but I don't know for sure.) I was obliged to reinstall it, and
had no problems for the next eight years.
When people say that Windows is crash-prone, and/or often requires
reinstallation, I have to wonder what's going on. I've worked many jobs at
Microsoft, and have never seen this. I can only assume it's due to some sort
of user error, or badly written drivers.

Yes, not from MS of course, even the Win 8.1 update is pathetic, and Classic
shell is just a patch for a problem that should never have existed IMO. Give

Linux is great if you are happy with the available software, or all you want
to do is surf the net. However I'm amazed that people who can successfully
install and run Linux can't keep a Windows box running.

Was OS/2 particularly crash prone, or are you referring to the fact that it

They are philosophically very different to run and debug problems on. With
Linux, you can readily look inside and see what is going on, and so step by
step diagnosis is possible (and in fact is essential). On the other hand,
with Windows systems you can't really see what is going on inside the box
at all and if you attempt conventional step by step diagnosis you will only
get frustrated and angry. Windows diagnosis is basically done with a matrix
of problems and solutions... and the good news is that there are enough
Windows systems that a google search on a given problem will usually find you
a solution. That doesn't mean the person with the solution has any more idea
what is going on inside the box than you do, though.

Hi there,
I am trying to appropriate the motors out of an old vcr.
I have a VEM0800 motor attached to a board with a BA6868FM chip on it.
The board is labeled VEP02579A, other markings on the motor include "EP23AA" and "403201"
This is the only data sheet I have for the chip is:
http://media.digikey.com/pdf/Data%20Sheets/Rohm%20PDFs/BA6868FM.pdf
Before I spend too much more time on this I was wondering if anyone knows where I can get a pinout for the 8 pin header on the board?
The assembly was given to me already removed from the vcr so I can't trace it back that way. If no one knows I'll go through checking continuity pin by pin, but I'm trying to avoid that.
Thanks,

?Nothing solid yet, but I would recommend getting a print for one of the VCRs that use this motor.
ther eis one here : https://www.partstore.com/CompatibleModels.aspx?MfgName=Matsushita&BrandName=Panasonic&PartNumber=VEM0800&ItemCondition=New&page=3
VCRs control these motors quite well and reverse them and all that so getting the print for any of the VCRs tyhat use that motor should give you the methoid of how to control it.
You could do it yourself from scratch if you want to reinvent the wheel, but do you ?
If so and you got good reason, say so. you could concievabvly connect to the motor board and discard their inadequate chip. But why ? I know they had a way to report the phase back to the servo chip but never looked into it. they did this for slow tracking. Rmeember slow trackng ?
Anyway, get the print for any of those machines and you should be able to do what you want to do. If not, say so...

Well I've never paid $200 for Windows, and I use a firewall. *IF* all the
software I choose to use was available for Linux, AND all the drivers were
available for the hardware I choose to use, I'd happily run Linux on my
computers. Been waiting for a couple of decades for that to happen, and not
holding my breathe though.

The Apple ipod itunes crap is the only problem, Windows works well with
every other MP3 player that I've ever used. But so does Linux for that
matter.

In the days when computing power was far more limited than it is now, it was
a neccessity. But since I've had no problems doing all my multi-track audio
work on generic computers for the last decade, I'm not in a hurry to go down
the expensive, locked in, hope they might give you what you want/need
someday path ever again. Because so many others agree is why those systems
no longer sell.
Some people might want a brand new Nagra tape machine too, but not enough to
make it a commercially viable business plan it seems.

The "throw more CPU power at it and hope it works" philosophy works fine
as long as there's plenty of CPU power for what you want to do. But how
long is that going to continue?

Dunno, Nagra seems to be doing pretty well right now. They don't sell a lot

Dead right. I'm not only amused but annoyed they find it necessary to mess

want is the fastest way to get to the applications (with support for all the

See, I would consider Solaris a lot more advanced, in terms of actually having
a solid kernel that has been well-debugged and is stable. Turn off the stupid
java gui and all that crap and you have a very solid OS that does not require
constant patching.
My complaint with Linux is mostly that the Linux community is constantly
changing things, and they often don't change them for the better or the
worse, they just change them for the sake of changing them. This seems like
misplaced effort on the part of developers, but what bothers me is that now
I have to change my stuff unnecessarily.
I would much prefer a system that was actually designed, where someone sat
down and made a decision about what the thing was supposed to do and then
built it to do that and then removed bugs rather than added features.
But... when systems are built like that, they aren't systems for everything,
they are systems for the one thing the designer decided it was supposed to
do. And if that's not what you want... that should be fine because there
should be plenty of other systems out there to do other things.
It's the lack of those other systems that I am bemoaning.

Every week someone finds some security vulnerability that needs to get
patched. Every week someone makes some unneeded change. If there is a
problem with a third-party device driver I can't call up DEC support
on a three-way call and have the DEC developers working with the third-party
guys to fix the problem.

No, you don't just write drivers. If you want an actual hard realtime
system you either need to wrest control away from the OS and do everything
as one uninterruptable process, or you need an operating system with a
scheduler that assigns timeslices to processes based upon how much time
those processes need to make deadline. When you make a call to the operating
system, say open(), one of the parameters is how long you have to wait for
the OS to do the job, and the kernel will prioritize the call appropriately
to make sure all those calls return in time.
The alternative is just to throw CPU at the problem and hope everybody can
meet deadline. This is called "soft realtime" and sometimes it works and
sometimes it doesn't. What is evil is that sometimes it's not always obvious
at the time that data is being lost because there is no way for the kernel
or the application to flag that it's missing deadlines in many cases.

Exactly, I specifically said "*tape* machine". Where are the new models?

Seems to be increasing true wrt audio, given the continued rate of increase
in CPU horsepower and RAM size versus software requirement on it. Even
CPU-hungry plugins don't seem to be the problem they used to be.
This applies to everything I've ever done, except for video-rendering which
is and probably always will be ever-expanding in the resource demand dept

Chicken-egg thing really. Features need to be added because of commercial
really - other products may sport such features (sometimes even good and
truely useful ones !) , and 'whatever' OS needs to keep it's user base to
survive.

And frankly, it's not something I'd consider a very real problem at

With apologies to Edgar Allen Poe...
Once upon a Tuesday dreary, while I pondered, weak and weary,
Installing the same version of Windows once more.
While I cursed the constant crashing, I made a fist and started bashing,
Started bashing the computer case and CD-ROM drive door.
"Piece of crap," I muttered, bashing the CD-ROM drive door,
"I will take this crap no more!"
Distinctly I do remember, when I bought my PC in December,
The marketing man said this software would crash no more.
Eagerly I wished to borrow a tool to inflict pain and sorrow
So that one day, perhaps tomorrow, I could go to my computer store
For the chance to make the salesman sell this crap no more.
Only this and nothing more.
So after wasting countless hours, I unplugged the beige mini-tower.
My day was looking very tragic like the old poetry of gothic lore,
But suddenly there came a tapping, rhymthic like the beats of rapping.
Actually, it sounded like flippers flapping, flapping at my apartment door.
"That is very odd," I muttered, "the time is nearly half past four,
Who is knocking on my door?"
The door was opened but it only revealed a penguin standing quite lonely,
Standing with a bag of CD-ROMs on the stoop before my apartment door.
I thought at first it was a delusion, for I was wrought with great confusion
Over the presence of a flightless Antarctic bird at my apartment door.
So I stood there, looking quite the fool, with my jaw down to the floor.
Then the bird said, "Pay no more!"
I thought to call the SPCA ... perhaps it escaped the zoo today.
But instead I brought the talking Aptenodytes forsteri inside my door.
He looked around, he looked at me ... and then he waddled to my PC.
I followed fast and I did see him place his disc in my drive door.
His program booted and began to install software I'd never seen before,
Then the bird said, "Pay No More!"
He brought me LINUX to install, said it rarely crashed at all.
Then he showed me some books while the software installed some more.
The interface, it looked like UNIX ... but 'twas much cheaper than QNX.
In fact, the code was open, so the source of bugs was hidden no more
It made wonder about the penguin's disc, behind my CD drive door ...
And why the bird said, "Pay No More."
So I tried this new installation, at first with fear and trepidation,
But soon I found it more stable than the OS I used before.
The files were in different places, and I put Linux through its paces
And very rarely made odd faces ... it didn't crash like Windows did before.
For this fat penguin made me see a way to use my computer as never before.
Then the bird said, "Pay No More!"
So once upon a morning sunny, I installed Linux for no money,
With the CD-ROM brought by a penguin to my apartment door.
After cursing the old installation, I reduced my overall frustration
And with a bit of determination I removed the software I used before.
Now I read Linux books and Web sites to use my free operating system more.
Quoth the penguin, "Pay No More."

I've been using Windows since 3.0. That version tended to crash for no obvious
reason. I've not had that problem with any later version.
Around 2004, "something" went wrong with my Windows 2000 installation. It
would boot, but its behavior was screwy. (This might have been due to a
malware attack, but I don't know for sure.) I was obliged to reinstall it, and
had no problems for the next eight years.
When people say that Windows is crash-prone, and/or often requires
reinstallation, I have to wonder what's going on. I've worked many jobs at
Microsoft, and have never seen this. I can only assume it's due to some sort
of user error, or badly written drivers.

Yes, not from MS of course, even the Win 8.1 update is pathetic, and Classic
shell is just a patch for a problem that should never have existed IMO. Give
touchscreen users the option by all means, but no need to remove what
already works for everybody else.

Linux is great if you are happy with the available software, or all you want
to do is surf the net. However I'm amazed that people who can successfully
install and run Linux can't keep a Windows box running.

I was there during the period of OS/2's brief popularity.
Was OS/2 particularly crash prone, or are you referring to the fact that it
needed the Presentation Manager for a graphic interface?

I took it as more of a suggestion that the owner and creator of
Microsoft didn't want to use a Microsft OS on his own machine.
Of course, it could just have been research to find out just how bad
OS/2 was....

They are philosophically very different to run and debug problems on. With
Linux, you can readily look inside and see what is going on, and so step by
step diagnosis is possible (and in fact is essential). On the other hand,
with Windows systems you can't really see what is going on inside the box
at all and if you attempt conventional step by step diagnosis you will only
get frustrated and angry. Windows diagnosis is basically done with a matrix
of problems and solutions... and the good news is that there are enough
Windows systems that a google search on a given problem will usually find you
a solution. That doesn't mean the person with the solution has any more idea
what is going on inside the box than you do, though.

Hi there,
I am trying to appropriate the motors out of an old vcr.
I have a VEM0800 motor attached to a board with a BA6868FM chip on it.
The board is labeled VEP02579A, other markings on the motor include "EP23AA" and "403201"
This is the only data sheet I have for the chip is:
http://media.digikey.com/pdf/Data%20Sheets/Rohm%20PDFs/BA6868FM.pdf
Before I spend too much more time on this I was wondering if anyone knows where I can get a pinout for the 8 pin header on the board?
The assembly was given to me already removed from the vcr so I can't trace it back that way. If no one knows I'll go through checking continuity pin by pin, but I'm trying to avoid that.
Thanks,

?Nothing solid yet, but I would recommend getting a print for one of the VCRs that use this motor.
ther eis one here : https://www.partstore.com/CompatibleModels.aspx?MfgName=Matsushita&BrandName=Panasonic&PartNumber=VEM0800&ItemCondition=New&page=3
VCRs control these motors quite well and reverse them and all that so getting the print for any of the VCRs tyhat use that motor should give you the methoid of how to control it.
You could do it yourself from scratch if you want to reinvent the wheel, but do you ?
If so and you got good reason, say so. you could concievabvly connect to the motor board and discard their inadequate chip. But why ? I know they had a way to report the phase back to the servo chip but never looked into it. they did this for slow tracking. Rmeember slow trackng ?
Anyway, get the print for any of those machines and you should be able to do what you want to do. If not, say so...
