Holy crap, that is an amazing haul. I would have taken it all too.
Would still love to thumb through some of the manuals!

360 Technologies is (was) and old HP reseller.
I just tried buying a 9145 from them, and didn't hear anything back.
Called them, and they are in the middle of selling off what they haven't
scrapped.
Mike is going to let me know more of what will be available and by whom next
week.

I just called, looking for a cable. Mike said they were selling the
building and the plotter side of the business, but it sounded like the
HP side might be coming back in some shape or form.

Thanks for that pointer; I don't think I've ever seen that - quite
interesting.
Alas, it didn't have the cache info - but now that I've though about it
overnight, I'm pre

Not sure that I know such a person but you might try hunting for the

Steve, Adrian,
I am pretty certain that alcohol will break down the binders and
remove the oxide. Since the bad disc was run through the drive the
head/heads should be cleaned before any more read or write attempts are
made otherwise more discs will be damaged.
Thanks,

Trying to identify the S100 serial board in my Imsai 8080.
https://imgur.com/eZyOVT5
I assume it was a kit. There are wires from behind one of the ICs that go
to DB25 on the rear, along with other DB25s with a few pins (maybe
cassette input.)
Any help appreciated.

No, no, no! Do not use isopropanol to clean floppies--you'll wind up
with a soft oxide coating and a brown rag. Were these mine, I'd first
remove them from their jackets and then bake them and then clean them
with distilled water and perhaps a couple of drops of a wetting agent

I'm thinking one serial and one cassette. The 8251 for the cassette.
I can't make out all the chips at the pins? The board was hand laid out. Is
there nothing on the bottom but traces?

The two connectors at the top remind me of the MITS 2SIO board. Chip on

use a UART (40-pin chip) and an ACIA, but it’s an interesting two-port combo
