Our Physics Dept. recently decommissioned their old Bomem Interferometer
computer, which was PDP-11/73 based. Somehow, when it got around to
what to do with it, my name came up. The thing is now sitting in my
cube. The only DEC cards in the box are the CPU and the disk
controller. Everything else appears to be custom.
One of the boards appears to be a custom multiport serial/EGA Video/PC
Keyboard interface that wants the console to be on the PC Keyboard and
EGA monitor. Unfortunately, none of the EGA monitors (NEC JC-1402P3A)
that I got with the system will power-on. You plug them in, flip the
switch, and nothing happens. Not even a power light.
I really have no need for all the custom stuff and would just as soon
remove it as use it. I do have a spare DHV11 here that I could put in
the box, but I do not know if the DHV11 can be used as a standard serial
console.
The DHV11 tech manual does not seem to have any info on using the board
as a console.
Any help would be appreciated.

Hiyas,
See above. I found some stuff that I can safely let go,
without too much heartache:
- several binders with manuals and periodicals from systems
from The DIGITAL Group, Inc. (*NOT* DEC !!)
- an Apple II Technical Manual
an unsoldered, virgin AppleII clone board, once sold by
Eijlander Electronice in Ede, The Netherlands. I never
got around to assembling it, so its still virgin.
- several master tapes from Informix for SCO Xenix/UNIX
- a whole bunch of silly 9600/14400/19200 voice-band modems
designed for (analog) leased line operation, including the
power supplies. The PSU's do +5V and +12V at 1A, so might
also be useful in other apps.
Cheers,
Fred

Here in Socal we have 5 going on 6 monthly or semimonthly old computer
often containing swapmeets. The first two saturdays of the month are Santee
and Fontana, which are either small or too far for me most of the time, but
I did manage Pomona last weekend, and TRW and ACP this weekend, and plan to
try for the new Chino Hills next weekend. The bad news is that space prices
seem to have risen enough to drive away most of the small non regular
sellers, and that most of the stuff is recent junk (Belkin is local and
TONS of returns get dumped to swapmeet sellers).
So what did I see, good stuff first, ACP had a pair of fresh from the shed
Imsai something 40 boxes with like 9 in CRTS on the front, and dual 8"
floppy box and a Selectric.
I didn't buy or even offer on any of that, sticking to a mini R/C tank and
some hifi cables. Pretty boring when the results of 3 swapmeets are just
some cheap parts.
Yes, I have received everyones emails about this gear. I am still working
out the particulars for who can get what, who responded first, etc....
I'll be in touch with all who expressed interest.

Stopped and looked through a bunch of scrap today. Found a Matrox VG-640
video card for the VME bus. Does anyone have any specs on this? Google
didn't find ANY hits for it.
Also picked up an AST Advantage card with the Advantage Pak
daughterboard. Anyone need it?
OT stuff: Also picked up a Beckman UV 5270 SpectroPhotometer. Man this
thing is loaded! Will try to re-assemble it and get it working in a few days.

Hi,
I just got an Epson RC-20 ...
with no software and with no cable :(
I'm looking for software, naturally :)
And, if anyone has a cable or information
about how to make a cable, I'd be interested!
thanks,

I have a couple 6 foot HP racks that will be available shortly. Pretty nice
racks actually. They are not the really old brownish/green racks, they are
the slightly less old cream colored racks. Nothing inside them :)
Finally got the system processor (TSB) back up to snuff with no parity
problems. Looks like the upper 8K of core suddenly got bit 12 stuck on.
That's easy enough to fix, barring a core plane failure there's only about 5
discrete components per bit on the card.
More exciting though, I got a 7906 drive up and working on the system via a
13037 rackmount box. Woohoo! The good news is the fixed platter (head 2)
formats fine and passes diagnostics. The removable platter (heads 0 & 1) I'm
not so lucky. I am not sure if the problem is the removable media, or the
upper two heads. I'll grab another piece of media shortly and find out.
This means that shortly I should be able to supply anyone who wants one - a
7906 disc cartridge with a complete set of HP diagnostics! I really need to
boot up DOS so I can dump the diagnostics library to bootable mag tape too.

Hiyas,
While going through Many Boxes (tm) of old stuff (yes, I finally
found the PC I was looking for ;-) I also bumped into some old
MSX home cputer stuff.
Any takes for this, before I make it fly straight into a dumpster?
Cheers,
Fred
