[RL cables]

It is just a bus. The internal drive cable is just a lenght of 40 wire ribbon cable
with 2 Berg sockets near one end and a single Berg socket at the other. The former
plug onto the backs of the external cable connectors. The latter plugs into a header
plug on the drive logic board.

There is one thing to be aware of. One of the 'corner' pins, I forget which one, is 
the +5V supply for the terminator. It is (obviously) not bused between drives. But 
of course you do need to power the terminator. So if you make up an oddball 
ribbon cable you should cut the appropriate wire between the controller and the
drive but leave it between the connector on the drive logic board and the conector
for the terminator.

It's a pity you're not in the UK, I have some RL cabling bits in the spares box. I 
could probably be persuaded to part with a twin-RL01 MINC....
