I just realized what it is...
It's the exerciser for CDC 5440 fixed/removable discs (OEMed to TI as the DS10)
..of which I have several which need work.
Has anyone made a list of what is returned by the CS/80
'describe' command (opcode 53) on the different models
of discs?
I think someone asked this a while ago, but I never saw
anyone reply.
Before I e-bay the following items, I'm posting a list here in case
anyone's interested in making a reasonable offer or trade. Items
are located in western Baltimore County, Maryland.
*** Local pick-up only, unless someone makes it very worth my while ***
*** to ship these items. ***
- Tektronix 4014 terminal. I may have some additional Tektronix-terminal
goodies, such as manuals and tapes, but for a different terminal.
Shipping this isn't trivial or inexpensive... it cost me well over $100
to have this shipped here years ago.
- Over 100 Sun VME-bus boards
- Dual expansion chasis with power supply for a Q-bus PDP-11 or VAX
- *Possibly* a spare RL02 drive
- CRT from an old DuMont oscilloscope
- Large drawer for a 19" rack mount chasis... may need some additional
hardware, but I may have it all, will look.
- Parts of a PDP-11/34A (front panel, boards, power-supply bits)
- Umax flat-bed SCSI scanner... doesn't work, but should be good for
parts
- 17" older HP monitor... very heavy.
Notes:
Tektronix 4014 terminal: Appears to need an HV PSU repair. Caveat: I
began disassembling this several years ago for cleaning and lost some
screws that attach the power supply to the chassis. Also, I misplaced
my notes about what wires connect where.
Although that enormous power supply heat sink is looking very tempting
for an audio amplifier project, I'll try to avoid the temptation in the
interest of preservation.
Sun VME-bus boards: these include several possibly rare boards such as
fiber-optic network boards, cable modems, color printer board, etc.
Finally, all of these boards are accessible and I've cleaned them up, so
AFAIK, there are no spiders, etc. hiding on them. It's my preference to
have someone collect them all at once so that I don't have to ship one
here and there, etc. Of course, make it very worth my while and I'll
consider doing that. :-)

I just ran across a Mindset RS-232-C module in some stuff that was
donated to our amateur radio club bazaar. A quick look didn't show the
computer it went with but if it is worth checking out, I can ask. Since
the bazaar is a fund raiser for our club, it is available for sale; any
thoughts on what it is worth ... and the computer if it should show up?
Our very own Chris Garcia has an interesting article on movie computers at:

For those who don't know what fanzines are, I will leave that up to Chris to
explain in some future issue.

So what would it take to kick off a CS/80 simulator
project for Linux or NetBSD - or even Solaris ?
--
It is creeping up on my interest list. This sort of started when
I won what turned out to be an incomplete HP PASCAL 2.0 source
document set on ebay a few weeks ago. There is ALMOST enough
information there to start on a simulation of the HP 9000/200
series, which is the most simple of the 68K machines that HP
built. So I've been digging around seeing what I can learn about
the 200 and 300 series over the past few weeks (DIO cards, et al)
and what software can be found (I picked up some 5" floppies with
BASIC and PASCAL a while ago)
I've picked up a couple of early 3xx boxes to take a look at (310,
320 and 340) and I just got a 9836 and 36C.
This was about the last of the machines that HP provided any sort
of technical detail on (schematics in the DIO card manuals, etc.)
Since the same cards were used on the HPUX workstations, there is
some information on them in the NetBSD code.
This also would be useful for a future classic HP3000 simulation
of the 4x series, which were CS/80 only.
I tried emailing Peter Brown about the work he was doing on raw
reads of CS/80 discs under WIN98 a few years ago to see what he
was able to learn, but haven't heard anything back yet.
Hi,
On a whim (hey, it's father's day :-) I decided to try and boot my
dormant 11/44 from the TU58 using the tu58 simulator.
Has anyone done this?
I'm being totally lazy and didn't look at the M7090 schematics (yet) and
assumed the TU58 20pin header is the same as the console 20pin header.
I also assumed it's RS-232 and not TTL. Further, I assumed it was
running at 38400 baud.
Naturally it didn't work right off the bat... :-)
I know my serial port and tu58 simulator are working since they boot my
11/730 just fine.
I'll look at the schematics but I thought I'd ask for any sage advice.
(luckily my spare UBI board had a DD boot rom on it)

Greetings, list(s).
First of all, let me say that I'm not in the habit
of making commercial posts; this isn't about that.
Also, this PSA is going out to several lists, so
if you see something severely OT please assume it
wasn't intended for you.
