I have a PDP11/84 (H7204) chassis available with the following boards:
M8190 - no cpu
M8191
N8637
M7556
M7547
M7860
M7860
M3105
M8789
M9202
M8648
M9302

unlabeled board
The chassis has the power supply, no cables. The front PDP panel has some
scratches and cracks. Operational condition is unknown, but the boards and
chassis look to be in great shape. Please contact me DIRECTLY with your
offer. Buyer pays shipping from postal code 99352 at around 100 lbs.
Thanks Norm Anheier

The ^mumble predates micros. I remember using ^O, ^S and ^X for
PDP-8 in '69 and the notation was existant then.

A local computer scrapper has invited me out to look at some stuff
he's got before he strips it and ships it out this weekend. He
described it as a "rack full of PDP/84's with tape backups". He
thinks there are three systems in the rack, and he mentioned that it
was used for some sort of telephone switching system. Does anybody
have any interest in saving this stuff?

I put my 85A back together today after fixing the power supply..Now it seems to be
DOA from a short circuit caused by a misaligned flexprint strip connecting the PSU
to the CPU board. The symptoms are:
The CRT works, but no characters are displayed.
Typing on the keyboard does not produce text either.
The chip on the left rear of the CPU board, just in front of the two flexprint
cables leading to the ROM drawer, gets rather hot almost immediately. None of
the other chips exhibit this heat problem. This chip is marked
"IMA8 0101 82055 SINGAPORE", and I believe it is the CPU because of the
connection to the ROM drawer. One of the pins on this chip is connected to one of
the traces on the flexprint involved in the short.
Questions:
Does anybody have a schematic for the 85?
If this is the CPU, what pins should I be looking at for the clock?
If the chip is shot, is there any way to get a replacement, or do I
have to cannibalize another 85?

I've come across a UNIBUS board that is seriously warped -- so badly
warped that some of the components directly on the curve have snapped in
half. I've seen others like it during various scrapyard excursions. What
causes this deformation? Can it be repaired?

I remember from my highschool days, the local
Computerland (remember those?) had a lovely
Onyx Z8000 machine that ran some flavor of unix.
I seem to recall it had most of the unix commands
available on the local university's PDP11/45 running
v7, and that the architecture somewhat resembled
a PDP11...
Anyone have this machine? It was strictly a business
box - serial ports, no bitmapped video, no video at all.
It must have been in the early 80's when Apple II's were
in vogue (and cost $CDN3000) and the Onyx was $CDN30K..
I could only find this blurb on a google search:
a.. 1980:Onyx introduces the Onyx C8002 microcomputer. It features a Zilog Z8000 microprocessor, 256KB RAM, tape backup, hard disk, serial ports for eight users, and running Unix, for US$20,000. It is the first microcomputer featuring an implementation of Unix.
cheers,
Heinz
I recently filled the car with these:
Apollo DOMAIN Series 3500
Domain series 3000 model 3010
HP/Apollo series 400
(2) Sun 3/60 + tape drive and tapes
Sun 3/50
Apple lisa 2
(2) apple II Ci
Mac SE/30 with radius monitor
Mac color classic
Quadra 610
Quadra 800
Quadra 860
power mac 7200/90
Also available was a volker Craig terminal, and a copy
apple's unix
I also have "quite a pile of HP 712/715/725s in various
condition" for me to pick up when I get some space cleared.
IKEA has said that the missing piece to complete the
shelving will be delayed another 3 weeks, and my wife says
no more machines until the shelves are up!
Is anyone with a good spare QBUS SCSI controller interested
in trading for a low-end Alpha? I'd also be interested in
a DSSI-SCSI converter.
