The Singer sewing machine company was doing exactly the same thing in the late 1800 early 1900. So is the motor industry, aided by legislation ! Though I can appreciate some of the safety aspects. There is hardly any manufacturer that isn't into this in some way or other.   -- Best Regards: Baron.

N_Cook <diverse@tcp.co.uk>: Sep 10 11:08AM +0100 Come to the end of the road on this. For spares purchase on ebay I suppose is the only chance. Main board problem , cracked die of a 100 pin Roland chip it seems. Common rail to this IC11 for the missing bank of keys is pin92. pin 90 is the common for the next bank of keys 33 to 40, which do sound. DVM-D and R checks on those 2 pins to 0 and 3.3V rail match as does powering up and both commons drop from 3.3V to 2.9v on a relevant key push. Any other ideas to persue?

With a fine needle make, as closely spaced as you can, random holes at the straight edge of the plastic, so the reverse looks like a cheese grater. Immerse the grater-end in some meths or similar and insert a few times into the socket. And also clean the end of the ribbon of course.

It's been working fine for several years running external hard drives for backing up files. Before using the new one I would connect a 12V bulb to the output as a load and see what happens when you apply power. Chinese quality control is almost non-existant, but when you get a good one, it seems to last. What do you expect for less than 10 bucks?

IIRC, maximum speed for that is 2Mbps.   Yep, however those were incorporated into the 802.11b specification. The two slowest speeds of 1 and 2 Mbit/sec became part of 802.11b when 5.5 and 11 Mbits/sec were added. <https://en.wikipedia.org/wiki/IEEE_802.11#802.11-1997_.28802.11_legacy.29> Besides DSSS (direct sequence spread spectrum) there were also a few FHSS (frequency hopping spread spectrum) promoted by Raytheon, Breezecom (Alviron), and TI. However, you won't see these in modern equipment, unless you include BlueGoof, which is FHSS.   -- Jeff Liebermann jeffl@cruzio.com 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558
