Yes. Don Maslin, who reads this list, will send you CP/M and a bunch of
other disks. He has almost every CP/M disk format known to man -- he does
a great job.

There were a couple different models of the Kaypro 4 (Kaypro reused their
model numbers even after making major internal design changes -- I detest this
practice of reusing model numbers; so far Kaypro is the only company I've seen
that does this). I think each needs a different version of CP/M.

Take the case off, and look for a number like 8x-xxx-x on one or more of the
chips on the motherboard. The last x may be a letter (probably A) or a number
or might not be there at all. Kaypro's part-numbering system was rather
erratic, it seems.

        81-240 original (1983? maybe 1982) Kaypro 4
        81-232 1983 Kaypro 4
        81-184 1984 Kaypro 4 (a.k.a. Kaypro 4'84)
        81-292 1984 Kaypro 4 (newest ROM version for this machine)
        81-296 Kaypro 4X (with super-high-density floppies)
        81-146 character ROM
        81-187 character ROM
        81-235 character ROM

There was also a Kaypro IV but in a quick search through my technical manual,
I can't find any info about it.

Get in touch with Don or wait for him to reply to my message :) and give him
the ROM version. He has CP/M, BASIC, Wordstar, MASM, etc. There's a URL but
I don't have it right now.

Good luck,
