RE: Extracting files off “unknown” 8 inch disks. Any thoughts…

Not really, in the event they would like them read and we know they are
RX02 there are a number of people here who likely could read them (myself
being one of them!)

I still think the best suggestion was the one about posting what's on the
printed sheet that appears to be a directory listing.  Better still, if it was
computer generated scan it and post the whole thng because printout
headers may assist in determing what the disks actually came from.

I apologize for being dense in this discussion, but it's pretty clear
that the disks are RX02 "double density" (I hesitate to call them MFM),
as that might confuse them with the System/3 MFM that's pretty much a
standard) and not readable by any hardware that the OP has.  As far as I
can tell, the donors no longer own a VAX equipped to read them.

The file system used is therefore of only peripheral importance, is it not?
