I have a large quantity of disks that I wish to copy to files
that can be directly used by the SIMH PDP-11 emulator and by the
E11 emulator. They include 8" floppies (both RX01 and RX02),
RL01, and RL02.
The issue is that the disks have sector sizes that differ from
the usual 512 bytes, as well
Hi Alan,
if you want to image your disks and floppies for use with simh, there's an easy
way to do it.
All you need is a (Micro-)VAX having the appropriate drive(s) running VMS.
MOUNT/FOREIGN
COPY/LOG yourimagename.img
DISMOUNT
Don't worry about the error message at the end of the COPY p

I'm very curious about what results the MOUNT/FOR & COPY method (under VMS)
will show with RX01/RX02floppies.I would try myself, but my RX drive is out of
order.I am confident in the virtues of VMS!Alan, let us know about your imaging

The issue is that the disks have secto

Hi Alan,
if you want to image your disks and floppies for use with simh, there's
an easy way to do it.
All you need is a (Micro-)VAX having the appropriate drive(s) running VMS.

Don't worry
Sorry, should of course have been the raw device:
