The 9100 scares me though. I really don't like having that HD in there.
Yeah, it's kinda cool to watch your test equipment boot HP/UX, but when
that drive lunches itself you're screwed. I double it's an easily
image-able format, and I can imagine a replacement from HP is in the
four-figure range...

I'd really like to see what it looks like. I got a 9100 surplus which I
passed on to ChrisR, but never did see the keyboard at the same place
(had the monitor though I think? Chris?). They have bins and bins of
keyboards though so I'd like to look through them knowing what to try to
find.

Yep. You are correct. The knob is cool. Probably the single best
feature over the 1630's. Someone was asking me about a Tek 1230? I've
never seen one-- not in my 1988 catalog either. :-/

The 1240/1241 had all sorts of funky features-- like "teleservicing".
You can remote control one from another by modem. Uses the RS232 port
and 12RC02 "Master/Slave ROM Pack".

Seems like there's some other technical difference w/ the 1241... Might
have had to do with memory chaining capability or something. The 1240
has a composite video output that the 1241 *doesn't* have though...

Funky, isn't it? If you "look past" it fast (without focusing your
eyes) the colors will be all screwed up -- kinda like seeing the refresh
on a monitor. It's odd...

RAM packs are out there for reasonable dollars. I had NO luck finding
the mnemonic packs (and they designed and built the thing here). I
finally had a Tek employee catch a want-ad from me and send it to the
"right person" at Tek and got in touch with someone there that knew
about them. He made me 6502, 6809, 68HC11, and Z80 packs in exchange
for a bunch of Diamond hardware I bought through my employee purchase
account. I'll look into making a multi-mnemonic cart 'cause I *know*
how hard it is to find the ROM packs! They're really cool, but a pain
to hook up unless you can dedicate some leadsets to a 40-pin DIP clip...

:-) We still have a 1240 here at Diamond (from our Supra Corp. days).
It's still useful and the only thing the engineers really like to use.
(the Tek is just soooooo easy to setup and use compared to the
HP16550...)
