My RX01 with a
DB25 was used with an 11/03 in an office back in the
late 1970s and 1980s. A null modem cable was used to connect from a
serial line in the back of the 11/03 to the DB25 on the back of the
tabletop RX01.
Serial line? AFAIK, the RX01 never had an RS232-type interface to it..
TU58s do have a serial connection (though maybe not at RS-232 signal
levels). I'd imagine you'd need a straight-thru DB25->DB25 cable to
hook an RX01 up to an RXV11 or RXV21.
Sorry, I realize that it wasn't a serial line. It just had an RS232 style
connector on the end. I suppose that DEC had wired up this thing so
that it used a DB25-DB25 null modem cable to pass the signals from
the ribbon cable coming out of the RXV11 controller to the DB25
connector (which connects to a ribbon cable inside the box) on the
back of the RX01 drive.
