What's the best way to slurp up DEC RX50s?

RX50DRVR would actually assign a different drive letter to be the "RX50"
drive. So you could actually DISKCOPY E: E: to copy one RX50 to another.
DOS DISKCOPY doesn't care about the format, so I think you could
duplicate RX50's this way no matter what system format they are in.
Also, a program that makes images from disks (I think they are many, but
I can't recommend any specific one) might be able to make an image from
an "RX50" drive that would work in SIMH. I'm not positive, but in my
mind it has a strong change of succeeding.

Hmmm.... Now to figure out where that driver might be...

I used to have a driver you could load under DOS called RX50DRVR that
would let you read MS-DOS formatted RX50's on a PC with a 5.25 1.2MB
drive. I don't have this program anymore, although it is possible I
might be able to search out a copy, and I don't know if it would be
helpful at all for non-MS-DOS formatted disks. If you're interested, let
me know and I'll see if I can scrounge up a copy.

What I would like to do is, with commodity hardware, not DEC hardware,
digest a large stack of (distribution) floppies. I don't care if the
solution is under Windoze or Linux. Either will work. I have a Teac
5.25" floppy working in my former main PeeCee that dual-boots to
Slackware or Win98.

I have TELEDISK, I have PUTR, I can probably have anything else if
required. I did notice a 10-sector floppy format special-device under
Linux. Wasn't sure if dd-ing from that device would work or not,
especially with the single/dual-sided issue.

Yes, I could probably do this on DEC hardware, but that would entail
spending way too much time in the basement where the 8200 is and its
console RX50s. If I do this on a PeeCee, I can be doing other things
while the disks gronk (but BACKUP/PHYSICAL would make it easy).

Primary goal is backup - TELEDISK should do that. Secondary goal is to
produce image files suitable for use with simh and E-11.

Thanks for any tips.
