RX01 is SSSD and most pc controllers are problematic with that
mostly due to cost cutting. Mest best would be a machine with
wd36c65 based chip (with both clocks available) as it can do all
rates. You will have to create you own driver for the SSSD.

I do it all the time with my CP/M crate (native 8" SSSD support).

The varios other 8" formats that did get used may require a
WD1771/and/or/WD1793 based controller (very non PC) to read
the possible and sometimes oddball formats used.

RX02 is a truly unique format and only RX02 (or the few clones)
actually can read that (you must have a PDP-8, PDP-11 or VAX
in other words) as most are Omnibus, Unibus or Qbus.
