In fact, I still have a group of RCA tapes with an cross
assembler and other tools (for /360 compatible RCA Mainframe :)
- We just need one of these 1966..75 build dinosaurs.
Or to be more constructive, I'm still able to read and write
1802 Assm (or at least I belive to be - it's some years ago :).
Writing 'modern' Assemblers (Z80, x86, MIPS, ARM etc.) isn't
tragic at all.
I'm just a bit far away from SD.

I have just had laid on me a very nice condition (from a bank) texas
Instruments model 911 VDT video display unit. I only have the screen
unit, no keyboard. It has two jacks on back, one marked keyboard and one
marked controller (9 pin male d-sub)
FREE to anyone that wants it, you pay the shipping of about 30 lbs. I
need to hear from people soon on it or it will go dumpster diving and
not come up for air. As it is I still have the Visual 102 (complete) and
DEC VT100 (no keyboard) to GIVE AWAY and the last inquiring mind never
got back with me. These are also in great condition and working order
and available for the cost of shipping.

I thought I was the only one who owned a TI-74. I'm looking for the
specs too. TI does mention some authorized service centers on their web
page for the TI-74. I haven't got a chance to contact any of them for
information.

One more question:
Does anyone know any technical dokumentation for the
TI PC-234 printer and/or the TI-74 interface ? I couldn't
find any usefull trace in the web.

I may be naive, but I understand that the satellite was owned by
a connecticut company who was have it launched to replace the one
which went bad earlier this year, knocking out millions of pagers,
etc.

So would I... and I would have suspect that such a satellite would have
been launched from vandenburg. This is part of the reason I do believe
it was a communicates satellite.
BTW - if not from vandenburg, then aboard a shuttle...

Actually, from the news report I heard, it was a new launch vehicle.
The maiden flight... That doesn't contradict the idea it may be old
technology, but supposedly the vehicle was one of a new series...

Someone here mentioned a few days ago that he had the drivers
for a hitachi cd-rom drive. Does anyone remember who it was? I want to
test this thing before shipping it.

Nope, it's not an error - it's the address the CPU stopped at. It's
certainly the case that at address 0, there's a "HALT" instruction
(i.e. the contents are zero.) This is very possibly because the boot
block you read into location 0 was all zeroes - i.e. not a boot block
at all.

I got one with an expansion box, monitor, and 2 disk drives for $2.50. I
also got a LOAD of software with it. It was working fine 'till the monitor
blew. I tried fixing it, and got it working, but it was a bit wavy. Then
the P/S for the expansion unit blew, so I sold the whole deal for $20.
