If it's of
interest, I have some pretty complete service data on Kaypro
8-bit stuff, including the schematics of multiple versions of the power
supplies used in them, though I'm not sure it was necessarily all of
them. I remember California DC (?), Astec, and I'm not recalling the
others offhand, but they're around someplace. _This_ stuff I don't want
to sell, but I might be persuaded to make some photocopies. :-)
Thanks for the offer. For the most part, I think MOST necessary parts of
the Kaypro service manuals are out there - 1484-d, -e, and -f versions.
Can;t hurt to check against what you have, though.
I recall getting some back when somebody (Micro-Cornucopia?) was selling them,
and they didn't happen to include the power supplies. Though in much of what
I encountered resoldering at the connector usualy took care of the problem.
I remember sending a couple of sets of them out to people, like Jack Brown
at FOG, when they were still a going concern.
On the EPROM, never heard of THAT one, but I can hunt
around in my
Pro-Files magazines and see if any ads pop-up, and any info. I HAVE found
ads for the HandyMan, but that's about all!
If you have the ability, dump the EPROM, and I can take a peek.
It would take some doing, I think, particularly since I don't know what chip
it is without peeling back the label.
Is it a 24-pin, or 28-pin EPROM?
It's a 28-pin part.
