Wow, I know it's not a DEC PDP but I was hoping at least a few people used the darn thing. Would it be better if I post in VCF? Thanks for any input.

Hah! Don't feel too bad. I've lost count of the number of PDP-11 questions
which I've brought here, only to hear a resounding silence (most recent case
on point, my query about Clearpoint DCME/Q4E's).

I worked on HP 3000 systems in the late '80s, and would like to find
one for my collection. A series 42 would be nice, but a series 37 or
micro XE would do. Any leads? I'm already aware of the one on Epay in
Florida that's been sitting at $1,725 for the past year.
I'm in central PA.

Mike - this would be a good complete system for you Mike and good
it has tapes.
that may have the little cartridge drive in it too but beware the
cartridge drives they seem to all have gummy capstans... I ruined a
fos tape put it in... got error... pulled it out and looked like it
was slimed with the 'black oil' like in x files! there is a work around
for this though using some glue and rings on the capstan roller after
you scrape the goo off. having the large tape drive is better
anyway. like this unit has.
Our aim here at SMECC is to get data off our old tapes fro the
company days and also our bulletin board system we wrote that had 100
separate boards, email, voting and poll system multi user chat we let
other 3000 system managers in the 80s use... it was really something in
the pre-internet days.
Mike - there should also be a full file of all the hp-3000 stuff that
Marlys Nelson developed
I always thought it would be fun to finally get a series 68 or 70
but... yikes the power bill would hit you and the cooling....Yikes!
for the same reason we want a series II or III or CX for the
museums display but to keep it under power 24/7 with a string of drives
costs $$$ and especially when you consider the air conditioning !
I have a 37 cpu and a 50 meg drive but of course need recon fig it
which means cold load tape as the other drives in the string are
missing I can not it past the point of disavowing the other drives that
do not exist. Fun time here with the manuals etc... I have not had my
hands on A WORKING 3000 for over 22 years I think. A lot comes back
but there are some head scratching still going on!
OK have the cart tape drive with goo capstan and have reel to reel
tape drive that when at initial power-up it just spins the reels.
What do we need?
spare cpu
more little disk drives 50 meg will not hold the store set from
1986
Known good reel to reel hpib tape drives 1600 bpi ok as that is what
our store set is in and any of the other reel to reel tape
distributions contributions and found stuff was.
I will keep an eyen out for east coast stuff for you and appreciate
if you keep an eye out on west coast stuff for us!
pretty fun with drop box we can share programs without having to
ship tapes to each other!

Mike,
I have a complete micro/37 that I'd be willing to part with. It
was last booted about 2 years ago when another list member was
trying to his a system running.
Is is mounted in one of the short / narrow HP racks with 3x670H
HPIB drives. I think the total disk size is about 1 Gb. That
seems like a ton for a system that small.
I also have a HPIB 7980 front loading tape drive, that I would
include in the deal. AND... I have the original 9-track system
tapes (FOS), some spare NOS tapes (let me know how many you'd like),
the original MPE documents on CD, and I could probably dig up
some MPE paper documentation as well.
I am in western NC but could be coaxed into meeting you somewhere closer
(possibly southern Virginia).
I'll take an offer but, be warned, I'm not giving it away.
Thanks,

Hi, does anyone know anything about the configuration of these boards?
(The document on BitSavers only covers the Q4B; the jumper configuration
on the Q4E is totally different.) They are 4MB quad QBUS memory cards;
PMI capable, I'm pretty sure.
I have two of them, one of which came out of an 11/84 (I never saw it in the
machine, though), and is so probably configured to run PMI. The thing is that
I stupidly mixed it in with the other one, and now I don't know which one is
which - and they are jumpered differently.
It doesn't have to be full (or any) documentation; if someone had one they
_knew_ was jumpered for, say, PMI operation, I could copy their jumper setup
(or see if one of mine already had the same).
If not, I'm going to start in on drawing a picture of all the jumpers, and
see what QBUS/PMI pins they are all connected to - looking at the card,
there's a big row of jumpers next to the pins the PMI is on, and the jumpers
are all 'on' on one card, and all 'off' on the other, so I suspect the one
card is jumpered for PMI operation, and the other, not.
So, even if there no documentation extant at all, we should be able to more of
less figure out what many of the jumpers do, and start making use of these
cards.
But any help/info would be gratefully received!

Does anyone happen to have documentation, schematics, or software for the
Quay 900? It's a system based on the Quay 90F/MPS single-board Z80
computer and two MPI double-sided 8-inch floppy drives.
The drives are MPI part no. 77618022, apparently a 9406 variant but not
listed in the drive manual on Bitsavers. I suspect the pinout is close to
the SA800/850 pinout (industry standard), but I was surprised to find that
none of the variants in the 9406 manual have a pinout similar to that.
