   What
non-DEC-compatible stuff out there can read RX02's?

 Obviously the original RX02 drive can read RX02's... as can all the
 DSD, Sigma, etc. Q-bus, Unibus, Omnibus compatible controllers.

 But what can read RX02's using a generic SA801-type drive and a
 PC-clone? 
 I'm pretty sure that you're supposed to be able to do this with a
 Catweasel and the utils that make a DMK out of them (Tim Mann's name
 comes to mind).

I checked my Octopus system, and it says it supports the following DEC 
formats:

RSX 5.25" 400k

VMS 3.5" 1.4M
VMS 5,25" 400K
VMS 8" 251K

VT180 5.25" 180K

RT11 5.25" 400K
RT11 3.5" 720K
RT11 5.25" 1.2M

Is RX02 identical to one of the formats mentioned above ?

You can also take a look at InterMedias site at

No VMS 8" 251K is RX01.

All of the others are fairly generic floppy controllers in the host system
as DEC generally used the 1793 or SMC chips that did formats reasonable and 
common.

RX02 is very unique.
