Try asking on comp.sys.dec.micro, comp.sys.dec, and/or alt.sys.pdp8. The
RX50s are _not_ "unique density" and can, in fact, be read by a
high-density IBM 5.25" drive. There is a variety of software available
to do so on the net, but I do not recall offhand whether there is
software available to read the WPS disk format (all of my DECmate IIs
run OS/278 and CP/M).

No, you'll only need one copy of KERMIT. As far as I know, there is not
a version of KERMIT for WPS (yes, there are DECmate kermits for both
CP/M and OS/278, but not for WPS). It may be possible to take a WPS
document from WPS to OS/278 or CP/M and, from there, to the PC via KERMIT.
Diskette images of OS/278 and CP/M are available somewhere on the net,
along with tools to build copies of the diskettes on a PC.
But I don't recall where, offhand. To run CP/M, you would need the
optional APU card, which contains a Z80, but OS/278 will run on an
unmodified DECmate.

Using a single copy of KERMIT on a PC, you can capture the serial port
to a file (by, say, issuing LOG SESSION or its equivalent and CONNECTing
to the port) then use WPS' document upload features (there's an uploader
called CX somewhere in the system; I don't remember how to get there
because it's been so long since I've used it) to pipe the document out
the comm port. I used to use CX to send documents to a VAX occasionally,
so I know it's possible.

This is KERMIT for OS/278; it won't run under WPS.
