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.

What sort of media are you actually trying to boot? Why do you think
it's got a valid boot-block?

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.

I used to have a Model 1. I believe the logical answer for why Drive 0 was
at the beginning of the cable was do that it was the closest to the
computer, ant it would make it less confusing for novice computer users:
Closest drive gets the boot disk.
As for the drive with a resistor pack needing to be at the end of the
cable, I disagree. I had a two-disk system, and both drives were
identical. I know that, because when I first got the computer, I plugged
the drives in, turned them on, turned on the expansion box, and turned on
the computer, and they worked. I tried the drives the other way (switched
them on the cable), and they still worked.
I'm also sure that neither had the resistor pack, because when I got the
computer, it was supposed to have 4 drives. There was, however, another
Model 1 with an expansion box, but no drives. The person who was selling
the computers took drives 3 and 4 off of the one that I got, and put them
on the other one. My friend bought it, and the drives worked on it, too.
