I recently picked up an RX50 for my MicroVAX II. It does not have the cable
with it to connect to the BA123 distribution board, however it seems to fit
a traditional PC floppy disk cable, is that all it needs?
AFAIK it's just a straight-through 34 way ribbon cable with IDC sockets.
It does not have an 'IBM Twist' or anything like that.
It should be possible to make one in a few minutes :-)
