Hi, I'm not unfamiliar with the various versions of the firmware of your
Kaypro 4, but the only person that comes to mind is Dave Dunfield. In time
he has collected images of boot disks of many machines. I arrange from a few
months of a PC configured to be able to read and write disk images 3.5 " and
5.25", but I live in Italy. Once you've got practice on how to use the
software to create boot disks is more 'easy to do that to tell it. If there
is no one else to may help you I can try. I'll give you references of Dave
Dunfield:
