They're not matched in the sense that a particular controller board is
set to work with a particular read/write board. Any (say) RX01 controller
with work with any RX01 read/write board.
What you can't do is mix a controller from an RX01 with a read/write
board from an RX02 or vice versa. You'd realise this if you tried to do
it, the RX01 uses a cable with 16 pin DIP headers to link the boards, the
RX02 uses a cable with 20 pin BERG connectors.
[Controller == the top board, hinged ot the chassis, read/write == the
lower board that the drives plug into]

There is some kind of voltage selection done by the cable that links the
15 pin AMP socket on the back of the PSU to the drive motors and fan. I
can't rememebr if you can strap a 230V PSU for 115V though.
What I can rememebr is that this darn thing uses a ferroresonant
transformer, and that the conversion between 50Hz and 60Hz is
non-trivial. I seem to remember it involves a transformer swap.
Of course once you've got the PSU sorted out, you then need to replace
the drive motor pulleys if you're going between 50Hz and 60Hz...
