No, this has just a single 28-pin (dual row header) connector. I don't
recall ever seeing a disk drive with a single 28-conductor ribbon cable.
I'll test some points on the card and see what I can find. Any particular
place I should check?

I've been
tinkering with this mutt LSI 11/23 system I've got and am trying
to get it running. It's a custom-built system that has a mix of DEC and
third-party boards. It's configured as follows--my apologies if I'm not
conforming to standard DEC notation here [notes in brackets]:
Cage 1
Slot 1: DEC M8186 | CAMINTONN 504 [1]
Slot 2: Dataram Diceon [2]
Slot 3: Data Systems Design A4432-4 | Grant Continuity [3]
Slot 4: Emulex TU0110401 [4]
Cage 2
Slot 1: Emulex Tu1110406 [5]
Slot 2: Grant Continuity | Digital Pathways TCU-50DYR [6]
Slot 3: MDB DLV-11J | DEC M9400 [7]
Slot 4: Empty [8]
Notes:
1. I believe the Camintonn card is memory
2. This has "RK:" written on the handle...an RK05 disk controller?
Probably a disk controller for something else that emulates an RK05 to
the software. What connectors are on this board? 3. The Data
Systems Design card has "DY:" written on the handle.
DY: is the normal device name for an RX02 8" floppy. Does this card have
a 50 pin header on it? If so, you might have got one of the cards that
does the RX02 format on normal (SA800-series) drives, which is just what you
want, I think. The system
powers up. There are +5V and +12V LEDs on the front of the
panel that come on, and I've checked these lines at the power supply and
they are good. One oddity: the terminal marked -12V is a perfect -0.00 on
my volt meter. WTF?
Hmm... Without a -ve supply, the serial ports may well not work
correctly. I would want to check this further (in particular, I'd want to
check the supplies to the RS232 (or whatever) driver chips on the DLV11-J
card.
