It appears I am clueless about Kaypro machines

list sent in 2009, and I tried that in all of them, to no avail.
The disk on the 1, at least, seems to work, as it knows when I put
in a non OS disk, and tells me, but nothing else. If it had a read
error, would it not tell me? It does move the head and such when I
insert the OS disk, so it appears to be reading it. Still, it never
drops to a prompt.
Your Kaypro 1 probably has the Universal ROM, in which case it needs
CP/M 2.2U1. There's a good working image (one of mine) on Dave Dunfield's
site. There's a CP/M ROM and version compatibility chart on 4-1 of the
technical manual:
