claims to be the toshiba part with the same number.

All:
I bought a couple iCom 5.25" external floppy cases on eBay but
they come unassembled (i.e., no internal wiring harnesses). Does anyone have
a copy of the schematic that they could scan for me? Thanks.

I *think* most of the books listed so far have found homes.
I'm awaiting confirmation on some. I'll dig through the
list to see what has NOT been requested and repost them
with the other books not yet listed.
Thanks!

It was an Apollo-designed processor.
My housemate at the time was at Sun, and there was much concern
that it would be a SPARC-killer (Apollo was Sun's major competition
up until HP killed off Apollo).

They came out just before HP bought them, who proceeded to
bury it in favor of HP PA.
I just reread your post. If you can post pics I should be able
to ID them. When I saw white cube with 8" floppy, I was thinking
tower. It's probaby an 8" floppy for a Xerox 820. The keyboard
is probably a later style one for a Star.
I just got a VERY interesting phone call from the US Department Of
Defense Cybercrimes division. I don't think it would be prudent to disclose
the details but this MAY turn out to be VERY important. They have several
HP 9845 tapes that they need to read. Can anyone help? Yes I know all the
problems about the HP tapes and tape drives. I'm the one that found most of
them so let's not rehash that. What I'm looking for is a working HP 9845
with a working tape drive preferably in the Washington DC area. Also
information about linking a 9845 to a PC or other modernish computer so
that any readable data can be transferred to a modern format. I know
there's been some discussion about trying to read HP tapes on other
devices. Has anyone tried to do that yet? I have several 9845s but I
haven't fired up any of them in a couple of years and I know none of them
have a working tape drive. I have rebuilt the drives on other HP but never
bothered to in the 9845s.

Sorry for all these little messages. But, if I had
to type everything into one BIG message, I would just
decide it was too much work and toss the whole lot in the
recycling bin! :-/ I'll try to cram more into each list...
