Dear community,
I dropped over an AVIV card (model number 50-860), which seem to be a qbus tape-controller for drives with GCR-encoding.
Two 50pin pin connectors typically used for PERTEC-systems are sitting on the front.
Except for thirdy or so shops, google does not show up anything about this board. Bitsavers does not contain any AVIV-related
documents, either.
Does anybody have docs or at least jumper specifications of this board? That would be of great help in order to make use of it !
Kind regards and thanks in advance,
Pierre

The PDP-9 will now execute the built-in diagnostic described section
3.7.7.3 of the maintenance manual. This diag copies the contents of
the AR register go through the ADR to increment the value, then to the
MB register and then back to the AC, AR, and PC registers. This means
that much of the I/O bus logic, the CP timing, the registers, the ADR,
and the Control Memory is working. Now we need to fix the core memory
controller and start debugging the rest of the processor and I/O.

Okay, VAX heads. I got an external SCSI cable for my VAXstation 3100 M76 and
connected it to my old Apple SCSI CD-ROM that boots pretty much anything in
my collection (Apple, SGI, you name it). At the chevron prompt,
>>> b/r5:10000000 dkb500:
-DKB500
[...]
OpenVMS (TM) VAX Version X7G7 Major version id = 1 Minor version id = 0
[...]
PLEASE ENTER DATE AND TIME (DD-MM-YYYY HH:MM): 13-JAN-2013 16:14
[...]
%SYSTEM-I-MOUNTVER, DKB500: is offline. Mount verification in progress.
It just sits there. So I tried it without the /r5 bit:
>>> b dkb500:
-DKB500
[...]
OpenVMS (TM) VAX Version X7G7 Major version id = 1 Minor version id = 0
[...]
PLEASE ENTER DATE AND TIME (DD-MM-YYYY HH:MM): 13-JAN-2013 16:20
Configuring devices . . .
Available device: DKB500: device type SONY CD-ROM CDU-8
Available device: DKA0: device type RZ26
%BACKUP-I-IDENT, Stand-alone BACKUP V7.2; the date is 13-JAN-2013 16:21:06.64
$
So far so good.
$ BACKUP/IMAGE/VERIFY DKB500:VMS073.B/SAVE_SET DKA0:
%SYSTEM-I-MOUNTVER, SABKUP$DKB500: is offline. Mount verification in progress.
And sits there again. What am I doing wrong? (Don't say use another CD-ROM
drive; this one works perfectly with every other computer I've used it with.
And why would it boot from it but not install from it?)

Hi
There are 11 S-100 LAVA PCBs and 8 XT-IDE V2 PCBs remaining in case anyone
is looking for them.

Thanks and have a nice day!

This is when I went to the U of D...I remember those Zenith terminals were
in most labs. I checked years later, "..any old Dec stuff in storage
someplace?" all of this stuff is long gone except for one Dec Line printer
II in the kitchenette of the Comp Sci annex building on West Main St.
I did get a few little DEC things, here's one:

I have a few ethernet cards from the pictured systems with the hard-coded
Ethernet addresses.
