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. http://vintagecomputer.net/browse_thread.cfm?id=561 Bill On Fri, Jan 15, 2016 at 10:32 AM, Robo58 <[email protected]> wrote: > Hi Fred, > > Thanks for the reply.
