Philip, It is an amazing thing you have done.
I used to have an 8201A with the PIC-Disk system that provided a full blown CP/M operating system. After losing that original computer and disk system to theft, I was left without access to 20 disks of CP/M files and programs and back-ups of my 8201A memory images for quite a while. I did end up resolving the situation by the use of some software called 22Disk, which let me gain access to the disks on an MS-DOS machine. But, I still had all these CP/M programs that were unusable to me. And now, I am wondering, would it be a relatively easy operation to take your M100 + CP/M solution and port it over to the NEC PC-8201A/8300 platform? Hoping it may just be a few differences in BIOS calls and I/O port mappings. This is definitely something I'd want to try to achieve. THanks for your work on this!
