DuoDisk 5.25 bug (ctrl-oa-reset)

[spector@vax2.concordia.ca (Mitchell Spector)]

	Was just reading one of my old InCider/A+ magazines and noticed
a mention of certain flawed Apple DuoDisk 5.25 drives. Notiably, the
random "eating" of disks triggered by a CTRL-OA-RESET. They said any
DuoDisk analog boards with the part number '676-X101' or '676-X102' are
at fault. Seeing that I have two DuoDisk drives here, I opened both and
found (with my luck) the first had a # '676-101' and the second '676-102'.
I didn't see any "X" (or any alphabetical marking) within the serial number,
so I'm not quite sure if I have these faulty drives. I'm also not certain if
these faulty drives affect only original copy-protected disks, or backups
as well. I'd like to know before I ruin my software collection... :/

	If I do have two faulty drives, how do I go about fixing the
problem? The article mentions having to clip two capacitors off the
analog board, but doesn't mention which (or where they're located).
