The RD53 I have here has the W1 and W2 in place, the
next three pins are
DS (drive select) ID settings, DS1, DS2, or DS3. I seem to recall that
the drive has to be set as DS2 to be the primary drive on an RQDX3
controller.
No. The floppies are DS1 and DS2. The hard drive should be DS3. If
your system has a second drive, however, you may need to set this to
be DS4.
Depends on what else you have and how it is all wired.
What system box? (BA23? BA123?)
Direct connect to controller? (Leprechaun box?)
Connection through signal card? (RQDXE? BA23 backplane?)
More info is needed.
