Jerome Fine replies:
The BA23 normally arrives (i.e. has as standard
hardware) a distribution panel for the RX50 dual
floppy drive and RD5n hard drives. A 50 pin flat
cable with a female header at both ends is used to
connect the controller (RQDX3 in your case) to this
distribution panel. The distribution panel has a
40 pin connection available in approximately the
centre (although only the connection headers are
visible through holes in the bulkhead between the
distribution panel and the area which holds the
floppy and / or hard drives). The cable to be used
is a 40 pin cable with a female header at both ends
and usually about 10" in length (when used in a BA23).
Actually it's a 34-way cable, just like the 34-way cable used for a PC
3.5" drive, though without the "twist" that most PC drive cables have.
The RX50 uses an almost-standard SA400-style interface
.
