While we're on the subject of dead equipment, I've got an 810 that
hasn't been working for over a year now. The problem is that it just
isn't getting power. When you turn it on, nothing happens. I know the
power supply is ok, because it works with my 850 interface. I also did
a continuity check on the on/off switch and that was ok too.
Does anyone have any clues as what to look at next? I don't have much
of a clue when it comes to hardware, but my roomate is a hardware
hacker and could probably help me out. Any help would be appreciated.
I would rather not pay Atari $$$ for an exchange when I could probably
get a new XF551 for almost the same amount..................

Jeff Donsbach asks about a Dead 810 disk drive that doesn't seem to be getting power.. power supply tests OK... You might want to (carefully) remove and replace the "side board" in the 810... it's the PC board mounted vertically on the left side of the drive mechanism (it's secured by a screw in the front, and another in back). The power flows from the jack in back of the drive, through the sideboard to the power switch, then back to the powersupply in the back of the drive. The contacts on the sideboard may have oxidized since the drive hasn't been used in some time... removing and reinstalling the connectors may help... Incidentally, the Exchange fee for an 810 is quite low (can't remember exactly what it is just now, but it's nowhere near the cost of a new XF-551), but you would probably be far more happy with the XF-551... it's faster, smaller, and stores four times as much on a single disk..!

Re: dead drive but power supply test ok. The problem on my 810 was the 40pin socket between the powerboard and the driver board was bad. My question was and still is how can a connector/socket go bad if you didn't take them apart? But it fixed the no power problem! How this helps. -roy y

How this helps. -roy y If you've ever taken the connectors apart (and probably if you haven't), you may have some corrosion on the pins. This happened a number of times. A combination of contact cleaner and a little sandpaper cured it. -dg- Internet: dave@sun.soe.clarkson.edu or: dave@clutx.clarkson.edu BITNET: dave@CLUTX.Bitnet uucp: {rpics, gould}!clutx!dave Matrix: Dave Goldblatt @ 1:260/360 ICBM: 75 02 00W 44 38 12N
