If you're referring to the large socket between the MMU and FP IC, then
it's a spare according to my DEC handbook.

No, I was trying to indicate that the CPU was an 11/23 not an 11/23+. So,
do I need some magic cable to go from a DIP socket on the CPU board to
this card? If so, does anyone have a pinout for it? I've managed to pick up an FPF11/M8188
(PDP-11/23 Floating Point
option) for my PDP-11/23, and I'm wondering if anyone here knows how
to set up/ configure this thing. It's a standard-looking dual-height
QBUS module, with a 2x20 pin header at the top of the card (with the
QBUS fingers pointing downward. I've got a non-+ 11/23 CPU board
that I'd like to get it to work with, currently stuck in a BA23
cabinet.
I hope I understand you here, but if you're trying to use it on a non
11/23 system you out of luck (OK, you can use it on a 11/24 too ...)
If you look carefully at this board, you see that the qbus finger are
only for the power supply of this board, there are no signals on it.
Everything else this board needs is coming from the 11/23 or 11/24 FPU
socket on the CPU module ...
Thanks!
