What is an RX52 floppy? I'll presume you mean the rather large dual
drive RX02. The DEC 8" floppies are RX01/2 and have their own internal
controller. That would make RX01 or 02 disk system very hard to wire
to a PC floppy controller, like near impossible.

FYI: The DEC RX02 DD format is not readable by any standard floppy
controller chip. RX01 however is standard 128 bytes IBM softsector
format.

RX50 drives are fairly easy to wire to a PC it is however single sided
and dual drive with one spindle. The later item will cause all mannor
of errors if the driver doesn't internally know the two drives have a
common positioner. However FD55s jumperd for slow spindle and only
using one side work better!

Compaticard can only read RX01.
