I am converting a 68008 HMI emulator back to a 68000 emulator. there are
2 headers that must be changed from 68008 to 68000
j1 and j2 i need a person that owns this emulator to pop off the
plastic covers and record the jumpers soldered on the headers
i can provide pictures to bitsavers of the 68008 conversion as well as
pictures of the 68302 hmi emulators and a diagram of the 68008 headers.

I've a request for a friend of mine.
He's experiencing vertical bars on the display, characters repetitions
and video shifting.
For example,
AABBCCDDEEFF
or
LOAD0 LOAD0
xxxx xxxx
The 5120 completes its post.
We suspect the video card shift reg or similar.
He told me he cleaned all contacts and cheched all the cards.
We need the SY34-0193 or SY31-0552 manuals.
Can someone help?
Thanks!

While I was waiting for the Ridge's disk to dump over a 9600bps serial
port, I finally got a chance to work on my 11/34. Picked it up last
summer and it was in good shape but the power supply was completely
dead. I've rebuilt the supply and last night I worked out the last few
kinks.
So at this point all voltages are spot-on, the AC LO and DC LO signals
are high (these are active low, right?) but I can't get the machine to
respond at all -- the "DC ON" and "RUN" lights are lit up brightly, and
the "SR DISP," "BUS ERR," and "MAINT" lights are glowing dimly. The
status register display is dark. The system does not respond to any
keypresses on the panel.
I'm getting better with UNIBUS stuff but I wanted to run this past you
guys before I whip out the debugging tools and start tracing things.
I've taken it down to a pretty minimal configuration, sans any memory or
other stuff. Here's what I have in the main backplane (all others are
disconnected for the time being) from right to left:
Slot 1: M7266 (CPU)
Slot 2: M7265 (CPU)
Slot 3: (AB) M9301 (bootstrap terminator) / (CDEF) M7859 (front panel board)
Slot 4: empty
Slot 5: empty
Slot 6: empty
Slot 7: empty
Slot 8: empty
Slot 9: (AB) M9302 (terminator)
The "empty" slots have Grant Continuity boards installed and the NPG
jumpers on CB1-CB2 are all present on the backplane. I've confirmed
that all the right voltages are making it to the backplane (and I've
cleaned up those damned Molex connectors as well, just to be sure). Is
there anything I'm missing? Anything I should try? Does this failure
mode sound familiar at all?
Thanks as always,
Josh
I'm with Microfilm Services, Inc in Wichita, Ks. We've been in business nearly 50 years, and have
to do some serious house cleaning. We are a microfilm service bureau and laser printing shop.
These industries have long relied on what is now old equipment. Our cameras were fed by PDP11/34's
with data coming in on 9T tape. Our laser printers were fed by 9T tape and Bus & Tag online interface.
At this time, we have the following equipment for sale. You good folks get the first crack at it.
Anything unsold as of Friday, May 1, 2015 will go on ebay. Anything unsold after that will go to
the recyclers. Make offer on any/all, buyer arranges freight for large items, pay shipping on
smaller items, from Wichita, Ks.
Laser Magnetic tape drives, 6250bpi, one available.
StorageTek 2920 tape drives, 6250bpi, two available.

Hello, this is my first time posting to this ML.
I'm trying to restore my old VAXstation 3100 / Model 76, to a more
stable working order.
One of the biggest problems, seems to be finding RAM modules for it.
I've been looking for them in various places for many years now, but
nothing has really come up.
I seriously considered making them myself, as I have pretty decent
skills in lay-outing PCBs, and electronics.
I also need those rubber grommets, that hard drive used to be attached
with to the chassis. The rubber seems to break down after twenty five
years or so, and they start to become goo, kinda like warm licorice.
Pretty much any periphery for the 3100/M76, like periphery, etc. I'm
interested in that.
Anything except the monitor, probably. I do have the GFX card in the
machine, but the monitors fetch huge prices, and a big heavy thing
like that, would cost a fortune to ship to Germany.
Oh right, I'm in Germany. I'd pay for shipping and all that, of course.
Cheers,

Hi Bill,
Screens, and the like (projectors etc), use a different color theory from pigments such as paint. One is additive color theory, the other is subtractive. You will be hard pressed to find a match between the two.
I?ll forward you and Al a photo showing the 7690 pantone chip places on my IMSAI case as a side by side comparison. Color-wise, it?s almost a perfect match.

I saw a few listings on eBay of the DIGITAL Remote Services Console.
I have one in excellent condition, and it would be nice to put it in use.
But so far, I have not been able to find *any* documentation.
Info on the four 25-pin sub-D connectors would be a great start.
They are labeled A1, A2, B1, and B2. For pictures in the auctions, I'm
guessing that A1 connects to a VT-style terminal and A2 connects
to the system console port. That implies that the B connectors are
intended to connect to modems.
But I do not want to connect anything until I've seen documentation!
Does anybody have info on this nice box?
thanks,
- Henk

Just out of curiousity, what was the failure mode? (Also, trying to figure
out of the failure could have killed things...)
BTW, is it in a BA11-K box, or a BA11-L?

Yes. All UNIBUS signals are active low _except_ for grants, if memory
serves...

Hmmm.

Sounds like you've got the variant with the real ("Programmer's") front panel
- that's a plus. Although it's too bad that variant doesn't have a
"HALT/CONTINUE" switch - it would have been good to power it on with the HALT
on, which would have prevented it from trying to do any bus cycles.
No response to HALT/CRTL, though? Although I'm not sure if it would respond
to that if it was in a double-bus fault loop (NXM on trying to respond to a
NXM).

Always wise... :-)
> Slot 3: (AB) M9301 (bootstrap terminator) / (CDEF) M7859 (front panel board)
Most 11/34's run those cards in slot 4, not 3 (probably to leave room for the
FPP/Cache in slot 3), but slots 3 and 3 are (AFAIK) identical, so it should
be OK to run them there.
> the NPG jumpers on CB1-CB2 are all present on the backplane.
Err, I hope that's a typo for "CA1-CB1" - tying CB1 to CB2 (+15V) would not
be good (although if you did do it, it should be harmless in this
configuration).
I don't really have much to add to Don's message, about the next things to
try. There doesn't seem to be a way to configure the M9301 to have the
machine halt on power up, which would to my mind be the ideal. It might be
worth throwing a 'scope probe on MSYN, to see if it's trying to do bus cycles.

I spent the last week trying to document some of my analyzers and ICEs. There
are tons of photos, firmware dumps and some new manuals on bitsavers under
appliedMicrosystems, biomation, hmi, futuredata, hp/te hp/64000 and hp/64700.
The HMI-200-68000 manual that arrived today had the 68K DOS software in the
binder, zipped and up now under bits/HuntsvilleMicrosystems
Has anyone ever noticed a pattern to the numbering on the underside of MMI PALs?
It would be nice not to have to lift the labels off them. The ones I indentified
were
B7304 14L4
B7320 16L8
B7321 16R4
B7830 20S10
B7840 20L8
Most are protected. Every once and a while I found one that wasn't.
I'd be interested in other AMC ICE firmware dumps to add to the archive. I've made
some progress identifying the buses and what the various chunks of firmware are for.
Next thing to do is trace the pinouts and see if the house-marked 6809 memory mapper
is a MC6829.
From looking at the manual, the HMI-200 is kind of interesting in that it can run
without a target. The Applied Microsystems units require a 'null target' board.
