Ethan,
I share the same experience in regard to DEC 4000 spare parts.
Apparently, the Futurebus systems were quite rare. Situation seems to
be such, that can get parts only , when you're lucky enough to obtain another
DEC 4000 system.
The spare parts problem seems to be so serious, that I know of people, who
won't let their DEC 4000 run, as they are afraid that boards or other parts my
become defective... knowing that it's difficult to get replacement boards.
Kind regards,
Pierre

(Hah...Just in time to join in when vax-ownership is asked!)
Hello folks,
my very first DEC computer has arrived - a VAXstation II/GPX in a BA123 enclosure from Jos Dreesen, which I just brought home from Switzerland last weekend with the help of my parents. Thanks again!
The original configuration of the system was:
Slot AB CD
1 ----KA630-A CPU----
2 ----some memory----
3 ----more memory----
4 -DELQA- ..empty..
5 -RQDX3- ..empty..
6 ----QDSS 4-plane---
7 ----QDSS 4-plane---
8 ----QDSS base------
9-12 .......empty.......
13 ..empty.. -RQ Dist-
As to mass storage, there is a RX33 floppy drive in the vertical bay and the system has one HDD frontpanel insert installed. It came with a dead (possibly revivable) RD53, but a fellow collector also gave me a supposedly functional one.
I assume the backplane is the original 4x Q/CD, 8x Q/Q thing that belongs in a BA123 as indicated by the lettering in the cardcage. To my understanding, this means the grant chain was broken in slot 5 (after the RQDX3) because there's no board in its CD half. I rearranged the cards so that the RQDX3 now resides in 4AB, the QDSS base board is in 5AD and the DELQA in 8CD (I hope I did get that serpentine configuration right).
After correcting an issue with the cardcage fan (which turned out to be just the connector inside the fan tray plugged in backwards!), I hooked up a crufty old laptop as a terminal but didn't get any output as the selftest always got stuck at "A", which corresponds to a keyboard/pointing device problem. This is supposedly normal since I have the VCB02 video option installed but nothing plugged into it. (I have yet to get myself a DEC keyboard, mouse and the BC18Z splitter box cable; at the same time, I'll be looking for a TK drive with controller and any other stuff I can cram in there.)
I can get into console I/O mode (chevron prompt) by sending a Break from the terminal but it's a bit annoying that I don't get to see the CPU version banner and the test countdown that way. Shorting pins 8 and 9 on the serial console connector didn't make any difference either (I have read it will cause some VAXstations to use that as console instead of the graphics display) - bit of a bummer considering that any humble SPARCstation who realizes they haven't got a keyboard attached will start using the serial console.
I have read the KA630 User's Guide, especially the meaning of the BBU RAM contents, and it doesn't look as if there is anything short of hacking the POST code and burning a new PROM that could be done about it, but if I have overlooked something, I'm all ears. Other than that, I'm off now looking for a MOP server and some netbootable OS image, perhaps NetBSD, for a start...
Yours sincerely
Arno Kletzander, DEC neophyte ;)

I use them frequently. OpenVMS and Digital Unix is the OS of choice.
I collect Qbus PDP-11s and MicroVAX and also have a selection of 3100
series machines (VAXserver and microVAX).
OS for the Vaxen are OVMS5.4, V7.3 and also Ultrix4.2. OS for the
PDP-11s is RT11, RSTS and unixV6.
Never considered Alpha as they are too recent for me. If I had
one it would be in daily service.

I'm fiddling around with the gEDA suite, and I'm finding that nearly
none of the chips I want to use - MC6809[E], NEC 675, some 74LSxxx chips
- have symbols in the gschem libraries. I have the 6809E and 765 parts
done, but there are several smaller parts to go.
After thinking about it, I seem to remember that this came up a few
months ago, and that somebody (Dave?) either had an extensive private
symbol library or knew of an online repository.
Anyhow, I thought I'd ask before I invent anymore wheels. Anyone
have pointers to "obsolete" and arcane part descriptions for gschem?

DEC 4000/AS8000 have interested me for a while- were there any other
commercially available general-purpose computers using the Futurebus+?
I know that most AS8ks probably don't have the Futurebus+ adaptor, but
it is available. Pity they are so big.

"Card Catalog" - ILS (Integrated Library System) please! They do so
much more than simple cataloging now. I realized how much of a computer
snob I was this week- my school system is considering replacing their
current ILS (Dynix Scholar, circa 1988 interface) with either Follett
or DynixSirsi. I have a hard time taking Follett seriously because it's
Windows-NT only.
I received this email today... if interested contact me off-list...

I Just today saved a Kodak KIMS workstation from being thrown in the
garbage. It appers to be a VAX based system produced by digital for
Kodak to be used as some sort of specalized
information management and photo editing machine. I was only able to
save the system itself.

Is there any kind of common failure mode for EPROMs? I've just had a couple
which are refusing to erase - I'm getting repeating patterns of bits which
refuse to clear (i.e. go high) under the eraser.
Normally they seem to erase in ten minutes, twenty at the most - these pair
have had 30 so far. Just wondering whether to keep baking 'em or just toss
them because they're junk...
(I've managed to find what I did with my nice eraser - but it'll still only
erase a couple of chips at once)
cheers
