Argh, oh well. That leaves the Alphatronix thingy.
That Emulex card sonds Q-bus to me. I hope you're
not planning on putting
it in the 11/34...
No, no, no. It is in the weirdest uVAX III I ever saw. 19" rack mount third
party case with a 40 slot Q/Q bus (first 3 rows are Q/CD and hold the KA650
+ 2x 8MB memory.) Then there is a fold out "shelf" in the front which hides
a TK50 and space for three drives. Then on the front are the standard VAX
drive protect controls and a switch block with the baud rates and other
items labelled.
Then under _that_ was a BA23 with a Vaxstation 3200 badge, another KA650
w/16MB and some other as yet unidentified boards. (all DEC, no SCSI)
[In case it isn't clear, a SCSI Q-bus card is on my Wish list... :-)]
Besides the 11/34 is stuffed to the gills. I couldn't fit another Unibus
card in there even if I wanted too! Once I get it into my house I'll be
able to inventory the cards and back planes (I believe it has at least
three if I really did see two bus jumper pairs in there.)
So this card is almost certainly a GPIB interface of
some kind. No idea
what bus is on the other end.
That's a help. The connector looks like the same short centronics type that
plugged into the back of the HP lab measurement unit (a rack like thing
with a bunch of GPIB plug-ins)
Well, there are several designs of sliders. With the
most common one, you
pull it out all the way and then fiddle with the locking catches on the
sliders to allow it to be pulled out. Make sure you have somebody to help
you -- an 11/34 weighs about 50kg.
This was what I was trying, all the way out to the point where the thing
can rotate, then there is what appears to be a last pair of catches (which
I push) and then it doesn't want to continue out. Weird. Well at least I'll
get another shot tomorrow when I take the van.
Don't put an 11/34 down on its back -- you will
break the handles on the
circuit breaker. Don't ask....
Ouch!
