The problem is that for DEC RX50s, they are _not_ 360K or 1200K 5.25"

tracks. They can be read in an ordinary PC high-density drive, but
they aren't the usual Windoze format. If they were, I'd just use 'dd'
as you suggest.
So... again... who here knows how to make 400KB images from real RX50s
that emulators will like? I have a wad of Ultrix 32m and MicroVMS
diskettes I'd like to spool off, in addition to a small quantity of
RT-11.
If I have to go with DEC hardware, I can; it will just take a lot longer
to do.

(If anyone has suggestions for
"imaging" 360KB
floppies, 1.2MB floppies and RX50s using PC hardware
running Windows or Linux or NetBSD, I'm all ears.
1) If it's a true 360K or 1200K 5.25" disk or 720K or 1440K 3.5" disk,
you can just type 'dd if=/dev/fd0 of=disk.img' and get a copy of it...
