Thing is, though, every floppy-based MINC I have ever
heard of has RX02
drives. The standard format for those is 26 _256 byte_ sectors/track, but
using DEC's strange double-density encoding. The only things that can
read them are either a DEC RX02, or one of the 3rd party controllers (the
only ones I've seen are for Q-bus) that were designed to read RX02 disks.
AFAIK, no standard single-chip floppy controller can read them.

May I assume that the RX02 drives, per se, are not the cause of the
read problem, but rather it is the floppy controller? This would seem
reasonable since the RX02s can reputedly read RX01 diskettes.
