Wow.
I didn't intend to buy any computer equipment this weekend but
ended up passing a church swap meet with a big sign that list
"compters" <sic> on it. Later in the day I spotted a pawn shop
that had a sign up that said "Collectable PCs - get them while
you still can!" Just how much temptation can one resist?
Anyway I'll divide this into two groups - stuff I know things
about already and stuff I don't have a clue about.
Stuff I know about
TI/99 Expansion box with disk/memory/rs232
Atari 520ST
Commodore 128 (spare)
Commodore Cassette (original)
Macintosh (M0001)
DEC Rainbow 100 Documentation in box
DEC Rainbow OS disks
Samda Word Processor for DEC Rainbow
25 RX50 disks labelled MICRO/RSTS - I don't knwo what they are
but I'm guessing they're not for the Rainbow. I really needed
some RX50 disks though.
34 C64/128 disks with programs
18 Apple II disks with programs
FORTRAN on disk for the TI99/4A (the first disks I've ever seen for
the TI)
EagleWriter II for the Eagle Computer
12 Assorted CP/M disks
17 8" TRS-80 Model II disks
Set of OS disks for Heath/Zenith Z-100
VisiCalc and a couple other Atari 800 disks
Various old PC disks
Some power supplies and RF modulators
Hardware Maint manual for Novell Netware/68
(includes info and schematics for almost all early novell hardware!)
Stuff I don't know about
IBM 6360 dual 8" floppy system (for what?)
TRS-80 TRP-100 printer
TRS-80 Color Graphics Printer
Commodore DPS-1101 Printer
Alphacom VP-42 Printer (for VIC-20 only it says)
NEC PC8801A (no keybd, disk drives)
Excelerator Plus Disk Drive (looks like for commodore serial bus)
MicroSci Disk Drive (Disk II clone, right?)
Timex-Sinclair 1000 with plug-in box on the back (RAM module?)
(I never realized from pictures how small these were!)
TRS-80 RAM module (looks like the T-S RAM module)
It was a fun weekend (glad I drive a van!)

RSTS is a time sharing system that ran on, hmmm, I forget. I think some
DEC mini. I've used it in the real world a couple times.

I was leafing through some copies of Creative Computing I had today and
just happened to see an add that was hawking memory modules, printer
interfaces and graphics enhancement plug-ins for the TS/1000. That's
probably what this is. Is it called the Memo...something?

Was it Memotech? they made all sorts of addons for the ZX81, hi-res
graphics cards, serial and parallel ports and RAM expansion up to, as
far as I can remember, 1Meg!!! BTW, is anyone interested in swapping any
UK Sinclair stuff for a TS1000 or TS2068. I'd love to get either of
these!

If you want to unload them and don't find anyone else who wants
them, I might be interested. The only reason I'm not more
interetsed is that none of my LSI-11s have floppy drives and I
don't really feel like going to the trouble of duplicating a
PRO. On the other hand, if I ever come across a PRO, it'd be
nice to have an OS for it. If I were you, I'd check the
vmsnet.pdp-11 and alt.sys.pdp11 newsgroups. You can probably
find someone there who could make use of it.

Tim Shoppa (referring to Micro RSTS):
Ahhh. I guessed wrong. I had thought that the strange Pro I/O
was what the Micro referred to, but obviously not.
As far as I
know RSTS was never ported to anything except the PDP-11
at least not a port that was marketed. My guess is that these are
for one of the DEC PRO machines. These machines had the small
LSI-11 implementation. At any rate, you're right, they're not
for the Rainbow.
RSTS was never released for the Pro's. Porting an operating system
to the Pro is made difficult by the fact that it's I/O subsystem
is entirely different than the more traditional PDP-11's. If any of your -11's have a RQDX1/2/3, then all you
need to do
is add a floppy to the controller. RX33 floppy drives (TEAC's
with the proper jumper setting) will also read and write RX50's.
Unfortunately, I don't have one of those cards. It's nice to
know they'll take ordinary drives, though.

Ancestor to Ami Pro. I first used it with Unix, found a DOS copy out by
some trash cans in Manhattan a couple of years ago, complete with
keyboard overlays and everything. DOS version works fine with Linux DOS
emulator.
17 8" TRS-80 Model II disks
Any indication as to what's on them?
TRS-80 TRP-100 printer
I can't recall that one clearly, but I think it used thermal paper?
TRS-80 Color Graphics Printer
Which one? The little one that used roll paper (CGP-115) or the flatbed
CGP-215?
TRS-80 RAM module (looks like the T-S RAM module)
That's be for the MC-10 Micro Color Computer.
