By the way, the RD53 is a Micropolis 1325 or 1335 with the
R7 jumper added to the logic board. Otherwise, the DEC
RQDX2 will not recognize the drive. I have never tried them
on the RQDX3 without the R7 jumper, but it might be possible -
probably NOT.
The RQDX3 will not "know" that the 1325 is an RD53 without the R7
jumper, either. I have added it to several (there was an AT&T PC
that had the 1325 as a standard option - I got to scrap several
at work many years ago and kept the drives).
