Also, RSX-20F can only handle RX01 format. An RX02 drive can be used, but
not an RX02 format diskette.

TOPS-20 has no support for the front end RX01, nor does WAITS (which loads the
front end from DECtape, not floppy). I doubt that TENEX does, since it runs on
KA-10 and KI-10 processors (front ends are loaded from the main processor, not
from their own peripherals). ITS on the KL-10 is like WAITS, AFAIK: DECtape,
not floppies. I can't speak to the CI$ monitor or Tymcom-X.
