Archiving CP/M 2.2 Source Code Programs to a PC (Fat or NTFS media)

Hi Bill,

Thanks for the reply.  Yes,  I have an 8" Shugart 800/801 and one or two 5.25".

I'm a little rusty on the older PC's.  So when you say that 386 to PIII's could read an 8" floppy, would those PC's have SD floppy controllers?

I did a quick look and the link for the Catweasel ( and the website no longer operational.

Assume that I can get an old PC and connect it up how would an "image a disk" program work?  Does it have knowledge of the CP/M files system and can read the directory and grab the files?  Would the program also be able to write to the PC's file system to complete the archive?

What "image a disk" programs would suggest?

Thank you

do you have a working 8" drive?  You can attach to a PC from the 386 through to Pentium III as a "HD 5 1/4" drive.  That's what I do.  You need the DBIT 50/34 adapter and image an disk program.  You can usually for CP/M disks just use the motherboard's built-in disk drive controller, but I also have a Catweasel if I need it for more exotic formats.  CP/M disks are very readable, any format I have ever encountered on SS disks has been no problem, assuming the disk itself is ok.

Here is a thread from my web site that describes the process, as I accomplished it.  There is more than one way to skin this cat, there is also a link within the thread with a downloadable how-to guide from VCF East 9.
