Dear Friends: I have a TRS-80 Model II, expansion bay with one extra drive,
and a daisy wheel printer. I don't exactly use this equipment much and
would like to ger rid of it. Any suggestions?
Thanks.

I just found two Epson HX-20 computers with expansion units, plug-in
printers and plug-in micro-cassette drives. I've seen lots of these
computers but not the other items. Can anyone tell me about them? What's
a setup like this worth? Everthing is in PERFECT condtion, but no books,
tapes or anything else included.

They didn't! I was working from them from 75 through 79 and help start
the computer repair centers in ALlentown PA and then in Bethpage NY
and while they did sell a few non tandy machines IMSAI, SOL, Vector
were never seen in any of those places save for when I'd bring my altair
or NS* to test out something.
Now it's possible that one of the independently owned dealer stores held
and advertized other machines. Even the Radio Shack computer centers
didn't start opening until the beginning of 78. The trs-80 was mid '77
and Tandy did nothing in computers before that.

Yeap, I have two of them. I love them.

Then go look at "http://www.intellistar.net/~rigdonj/hp9807.htm".

Only a ****VERY*** minimal system was run out of the built-in ROM.
Usually HP-UX was run from an external hard drive or the built-in floppy
drive. There was a plug-in ROM available that contained a complete HP-UX
system. It was called the "Software Engineering ROM". It was optional and
VERY rare. Disk based BASIC was available for the IPC and was also
available in a plug-in ROM.

Have three older terminals, condition unknown but in good physical
shape. They go to the big mainframe in the sky if I don't get an
interested party by March 15th....
Digital VT100, no keyboard
Digital VT220, no keyboard
Visual 102 with keyboard
I'm going to ask $5 for each plus shipping to more or less cover the
time involved in packing and running these to the shipper, but otherwise
they're here and awaiting some interested foster home to contact me
about them. Neither weighs a lot but due to the glass crt they aren't
featherwight either.
COntact me directly. I'm in the process of finishing my new shop and
these are NOT going into it and taking up much needed space.

Yeah, but it could also be a Winchester drive, (external?) I think that it
was the first hard drive to use technology still used today.

I think you guys were right after all. It's a futile endeavour.
I just trashed the AT case and the entire PS/2 system except the
drives, cards, and ribbon cables. I couldn't stand it anymore. I will
pick up another case, there's plenty left that are not necessarily
PS/2. The thing did have an expansion card that had 2 MB RAM on it,
I will ship it to anyone who wants it.

I've been revising my web site a bit recently. One of the things I've
added is the entire 1978 Tandy Computers catalog which features such
things as the IMSAI 8080, Sol-20, Vector 1, etc. I don't know about
you, but aside from this one catalog, I had no idea that Tandy ever
sold anything like this. At any rate, the whole thing has been
scanned and put on my web site. I tried to keep the page images small
so they don't take forever to load, but it means that you can only
read the tag lines and prices. Still, the pictures and prices are fun
to look at. Take a look and let me know what you think. If there is
sufficient interest, I might go back and scan the pages at a higher
resolution and link the bigger images to the current ones. Also, let
me know if you see any glaring errors on my site; I'm still tracking
down some minor formatting problems, but most of it should be fine.
Just pick the "classic computers" link on the first page and go from
there to see the catalog. Hope you enjoy looking through it as much
as I did!

OK, despite your warnings, I pulled my AT motherboard out of its case
and put it into the PS/2 tower case. It fits reasonably well
physically, but I AM having a bit of trouble with the power supply
conversion. I have pretty much figured out how to wire the psu
to the motherboard, but the problem is the power good line. What
is it, and what would I need to hook it up to for the PSU and MB to
think that the power is good? (this is line 1 of P8 on most AT
motherboards)
