It has the 18 bit Q/CD backplane, I have another 22 bit Q22/CD backplane
in the closet here, holding a bunch of cards.
Anyone got the little short 9270 or whatever it was that had the power
supply and 4 full slots of Q18 (or maybe Q16. Hm. I wonder if I ever ran
an 11/23 in it). That would suit my needs, then I could let this guy go.

Chris,
I honestly have no idea. Does yours have the 8-slot H9278 backplane?
My 11/23+ uses a 9-slot H9276 Q/CD backplane. I don't believe H9276
will fit in an 11/03 box though.
I once tried to get an 11/23 up and running using an H9278. It worked
fine until I plugged in the RQDX3 board.
I probably missed something in my reading but it seemed like it should
work. The RQDX3 died though.
I still have that H9278 in a box, but I don't plan to use it. If
anyone wants it...

to say fire up an 11/03 with the WCS11, not sure if that combo would
work in a BA23 Q22 type backplane.
Does the 11/03 quad work in a BA23's Q22/Q22 slots? Will it blow
up if
half of it is in a Q22/CD slot?
