You'll need to do some more research, but here goes... You need to
ID the backplanes for sure so that you don't blow something up.
Three chassis:
BA-23: complete with outer shell and end caps. It bears a
"MicroVAX II" label on the console switch panel, and has a
floppy drive (dual disk) installed in it.
22-bit, for the MicroVAX II CPU you have
I don't know the model numbers for the next
two:
- One looks like a BA32 but smaller, and has the "3-switch" PDP
console/display panel on it. The cards are inserted from the
front beside the panel.
Likely an 18-bit backplane for the -11/23 CPU.
- The last one is the smallest, looks much like the
one above,
complete with 3-switch console/display panel, however instead
of metal side/top/bottom plates, it has a "wire cage". It also
has a second expansion chassis of similar construction with no
power supply or console panel.
I'm guessing this is a 16-bit backplane for the -11/03
I've also got the following third party cards - I
don't know
anything about these, other than the identifying marks found
on the boards listed below - if anyone can provide more
information on these, that would be helpful: (Several of them
appear to be media controllers of one sort or another).
Andromedia Systems UDC-11 rev H (50 pin connector at front edge)
Micro Technology Inc. MSV05B (x2) (50 pin connector at front edge)
TD Systems TDL-11H/A (50 pin connwctor at front edge)
Xylogics "Wizard 1" (50 pin connector at front edge)
SDC-RXVZ1 "8202 FD Controller" (50 pin connector at front edge)
Have you Googled these? Google Groups aka DejaNews will be the most
help. The first three *might* be some sort of SCSI, if so I'm
guessing that second one talks to tape drives. Can you provide
pictures of the 3rd party boards? Those are more useful.
Versatec LSI-11 P/P Interface (40 pin connector at
front edge)
Useless, it's for a Versatec plotter.
Did you get any drives with any of this stuff?
