Ok, I have this CX-11 which is a half rack full of backplanes & flip-chips
Are you suree it's a CX11? I have a pair of DX11s which sound like the
same thing. 8 rows of flip-chip cards, a sparate PSU and IBM power
interlock panel. I havea printset for it somewhree 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
straictly a slave
device on the IBM channel. In optehr words, it will let a PDP11
communciate 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').
