Floppy Disks and the IMSAI 8080

[bhall66]

I wrote an article about my reacquaintance with the floppy: system disks, blank disks, disk images, etc. I hope it is helpful to newcomers like me.

This looks excellent! Can't wait to read it in detail.

Very interesting read, very well written. Just had a look at movcpm on a current dev system, looks like I forgot to rebuild movcpm with the latest B03 BIOS, still contains B02, as you write. Good catch, thanks, need to fix this.

An updated IMSAI CP/M 2.2 disk with movcpm including BIOS B03 is available here:

Will this work as is on the IMSAI? I seem to recall that there is some difference in that disk (cpm22b01)

Yes will work, technically this is cpm22b03 with a better BIOS than versions before. If you are using an older one you should update to this. If you already are using cpm22b03 update too because of the updated movcpm program.
