I aquired an aged BA-123 a while back. It has an RQDX3 and the
interesting "distribution board" for the MFM disks.
The floppy (dual RX50) has a cable coming out of it which just hangs in
the air.
I'm guessing that some kind soul removed a card which some how connected
the floppy cable to the disk distribution board. I say this because at
the end of the BA-123 backplane there is a spacer and then two "qbus
like" slots. The bottom slot has the MFM disk distribution board
connected plugged into it and the top slot is empty.
Anyone have a clue about this?
I'll probably ditch the RX50 in favor of a stock PC 5 1/4" drive but
I'll still have to connect it to the RQDX3 somehow.
thanks!

That distribution board has a connector labeled RX50. The RQDX3 has a 50 pin
cable that goes to that disti board and from there you should have the usual
rats nest of 34pin (floppy), and 40/26pin (hard disks) from the distibrution
board to drives.
While your in there check the fans!
