I agree that it is not difficult to transfer individual files
to and from CP/M if you are familier with the tools ... in
this particular case, I need to archive and transfer 50+
complete disks ... This is from a rather obscure system
that was used in a Canadian university, and a museum in
Toronto wants exact copies of the disks. This program provides
that, and will be MUCH less work for them to recreate the
disks (one command/disk instead of multiple commands to
transfer dozens of individual files per disk).

  I've got a "Disk/Software images" section on my site where
I have begun to put all of my tools for backing up and restoring
diskettes. This includes 4-5 tools that I have created for
various systems, as well as a number of other tools that I
have used. I also have quite a few simulators available which
sometimes can really help with building that first system disk.

  I think it is an excellent idea to collect all of these
tools together into a single resource. If you have material
to contribute, please forward it to me. Or if you (or anyone
else) would like to put together a site more specifically
oriented to transfer/archive techniques, please feel free to
use the material from my site.

Regards,
Dave
