A few month ago I acquired a VAXstation 3200. It runs
runs very nicely
with a Emulex UC08 SCSI-Controller off a 1GB full-height SCSI-Disk.
There is one QBUS card in the system that I can't identify.
As far as I know the VAX has been used for measurement data aquisition
in a physics laboratory.
The only connector to the outside is for a 40-pin ribbon cable. I got a
very long (10m I guess) cable with the box so I suppose it is using
some
kind of differential data transmission.
Unfortunately I don't know what was connected to the other end of the
cable. Probably the card is useless without that second part (maybe a
A/D-Converter?).
The board occupies all 4 slots and is populated mostly with small ICs
of
the 74xxx series and some PALs.
The Label says:
KINETICSYSTEMS
MODEL D1571
MODEL 2922-Z1B
I did not find any usable information on he net. Does anyone of you
know
what this board does?
Thanks in advance,
Sebastian
You have the Qbus part (KSC2922) of a KSC2922/3922, Qbus CAMAC
interface. CAMAC (Computer Automated Measurement And Control) is an
instrumentation system extensively used in the nuclear/high energy
area. The other end of the cable that you have connected to a rack in
which various and sundry instrumentation modules could be placed. IIRC
the CAMAC bus was 24 bits and the hardware that you have either packed
the data 24->32 or various other packings. The basic standard is IEEE
583. There are a number of standards covering a serial interface as
well as software APIs.
What you need now is to find a CAMAC bin and the other end of that
interface and you can become a nuclear terrorist ;))
