the connection from the controller board (UNIBUS or
QBUS) is a
straight cable AFAIK. The RX01 and RX02 exist as a table top box and
uses a DB25 connector to the controller.
Not all RX01's have a DB25 to connect to the controller, on the ones I
recovered with an 11/23 system (rackmount drives), there's just a
ribbon cable connecting the two berg connectors on the controller and
drive together.
The ones with DB25 were used with Decmate-1 all others only had a
ribbon cable exiting the box at a bracket to support the cable.
the DECmate-1 version FYI still has the same baords and cable
hookup internally so it is usable with any system (after setting
internal dipswitch).
