Hi Dave
Hi Dwight,
I have used the serial port to transfer information
but once I have the basic core working, I just transfer
files. If it is a binary file, I've used Intel Hex
format and DDT to save to a binary.
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).
It would be interesting to compile a web page with
all
the different tricks used to handle the various image
and file transfer problems of these older systems. Things
like how to connect a 8 inch disk or a little source
code that shows how to do console to disk transfers using
the CP/M bios. One could include things like my H8/H89
image transfer program and my Olivetti M20 disk image
building code. I have code from another fellow to move
Polymorphic disk images from a Poly 881x to a PC with
xmodem( windows supports ).
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
