Ok, I have
this CX-11 which is a half rack full of backplanes &
flip-chips
Are you sure it's a CX11? I have a pair of DX11s which sound like the
same thing. 8 rows of flip-chip cards, a separate PSU and IBM power
interlock panel. I have a printset for it somewhere and maybe a
diagnostic source listing, but not much elase.
and has also a half sized lights top panel.
It's a Unibus controller to
talk
to an IBM bus and tag device. There are 2 large 'In' connectors and also
2
'Out' connectors. I do have a manual which describes some generic IBM
info,
but I would like to know what kind of device(s) could (if possible)
directly
be connected to such a thing?
From what I could deduce from the printset, this
is strictly a slave
device on the IBM channel. In other words, it will let a PDP11
communicate iwth an IBM machine, but it won't allow you to connect IBM
peripherals to the Unibus (you need the IBM machine to act as a channel
'master').
Yes, it is as you describe, several horizontally rackmounted backplanes
with a dedicated PSU. I have a FS printset and a user manual.
