If you lack the skills to do this, you're a hack.
It's that simple.
I've been doing this for 50 years now.
I don't lift traces, or break off terminals unsoldering
things.

The idiot's a troll. Look back at his previous interactions with others
here and elsewhere and there's an unmistakable picture that emerges. I've
KF'd him. You can waste *so* much time on pricks like that if you're not
careful.

No, specifically you said and I quote: "I pointed out that you're a hack"
which implies you have some sort of superior cognitive ability which the
regulars here don't possess. Like as if everyone else needs an obnoxious
*MORON* like you to spoon feed them the obvious!

And there you have it...
You're a hack. You just said so yourself.

That's your opinion.
My opinion is that you're hack.

yet another example of your dishonesty in attempting to convince people of something that has no ground in reality. You have become not worth reading. Bye.

As others noted, it is a thermal fuse.
 
The turns are there for pliers or other tool to absorb the heat while
soldering the thermal fuse to the PCB. It's quite easy to blow a low
temperature rating thermal fuse while soldering.
 
What't the schematic like, are the resistors connected in such a way
that they would heat during some failure condition and blow the fuse ?

It's even harder...ladder logic isn't a "cpu machine language" as such,
it's an interpreter running in some native cpu machine language...so
there would be a whole other layer of translation involved in order to
produce anything a human might be able to comprehend. Unless your
computer is made from relays...but why bother.

That's the packaged controller.
It contains a CPU.
The CPU interprets some ladder codes.
 
It's highly unlikely that the information required to decode the EPROM
has ever been published. This sort of thing is usually trade secret.
 
If the CPU is known, and the interpreter ROM is read, there's some
possibility of using a decompiler.
etpm@whidbey.com: Nov 21 05:35PM -0800

I'm pretty bsure this is a real long shot. I have looked online but
have not yet found something that will help. So I ask here.
The EPROM reader/programmer arrived yesterday and it works fine.
The UV EPROM eraser should be here in a day or two. Amazon apologized
for the delay. So I can copy the EPROMs just fine but I would really
like the ladder programs so that I can make some changes to the
machine.
I understand that the decompiled ladder will noit have mnemonics
but maybe I can decipher it anyway.
The control in question is a FANUC 3T.
Thanks,
Eric

Just be aware that sometimes trash is included in EPROMS to stop what
you are trying to do!

Ok, my previous post concerned the outlandish prices for some neat
looking HV devices originally from the late 90's: Luminglas discs. I
was successful finding several, and at good prices comparable to what I
would have paid in 2000 for some nice used ones. However.....
 
I have been on a new quest to try and find a large plasma ball. True,
they are all over the Internet, but the most common sizes seem to be 8"
diameter or less and I am looking for 12" diameter or more! However,
the price seems to increase maybe as much as 20 fold going from 8 to 12
inch size! I see some on eBay in 12" size for just under $200, but I'm
hoping to do better. Problem with the used ones I see is that the
sellers don't specify globe size and 99% most definitely are 8" or less
diameter.
 
 
Suggestions would be welcome. One thing I tried googling for was some
sort of a history on plasma globes with maybe larger ones from the past
mentioned. Other than Spencer's 12" Megavolt, that's all I could come
up with (and, incidentally, the person wants more for the Megavolt than
a new 12" one!).
 
Thank you.

The very large type you see in science museums and such are probably
custom jobs I don't think there's enough demand for globes of larger
size to make an industry of selling anything but one-offs.

I'd perhaps talk to someone on the facility of a place like which has
one, might be able to at least find parts or who made theirs. I'd be
prepared to pay a few G at least for a two-foot diameter one or such....

Just wanted to update that I now actually have thee of the Luminglas
displays! Although eBay prices are out of this world, I found all of
these either on Facebook Marketplace or Craigslist and all for less than
$50 each. A lot more reasonably priced! I remember them charging
anywhere from $25-50 back in the late 90's early 00's when they were in
Spencer's and elsewhere. If they are indeed collector items now, I may
have three chances in the future to sell if I ever grow tired of them.
