Does any know if the RQDX3-AA controller is supported
by RT11v5.4 b, or
do I have to get an upgrade.
It'll work just fine starting with at least V5.3. However, if you're using
this commercially you really should look at replacing the controller with a
SCSI controller, though you might want to keep the RQDX3 in the system for
the RX50 floppies. I personally consider it very dangerous to trust data to
MFM Hard Drives considering thier age. I'd recommend either a CMD or Viking
