I recently acquired a machine that contains an Emulex CU02. I suspect it is
a Qbus SCSI controller, but I am not sure. I have not been able to find any
information on this card, all my searches find is dealers selling them, but
no description. Does anyone have any pointers to information on this card?
Thanks

Hello Rob,
The PDP-11 module field guide at
http://world.std.com/~mbg/pdp11-field-guide.txt says it is a SCSI disk
controller that emulates an MSCP controller for one to four disks.
Nice find.
Cheers,
Christian

I searched that document for CU and CU02 and couldn't find it... can you point out
what line number it's on?

I have the field guide, but I can't find reference to the CU02 in there. Which entry
are you referring to?
Thanks
Rob

I think you must have misread something. The CS02 is definitely a comms
controller. It emulates a DH11/DHV11. The manual is on bitsavers.

Bah, I really should quadruple check what I type with this *wonderful*
vision disability of mine...
I swapped the letters and didn't catch it. UC02 is the QBUS SCSI
controller not the CU02.
Sorry about that.
Cheers,
Christian

Sorry to disappoint you, but a CU02 is a communications controller.
It's a serial line multiplexer, which IIRC connects to a pair of panels
that have some RS232 ICs and DB25 connectors on them. I don't have any
docs for that one, but might still have docs for a CS11 (which is a
Unibus version).
Emulex disk controllers have SCxx and QDxx designations.
