The pins used in the DB25 (and the 37-way) are arranged at one end of the
connector, in such a way that I am wondering if they're arranged to be easy
to crimp a matching connector onto a ribbon cable. And I seem to remember
that only the alternate pairs of pins are used on the RX02's 40-way Berg.
 Hmm, looking at the M7744 there seem to be 11 signal lines, so that idea's
not quite right. Time to dig out the print set, I think.

Yes, I've found the User Manual now, and it gives the DIP switch settings
for use with RXV21/RX211, RXV11/RX11/RX8E, and RX28.
