I may need your help in the near future. I just
aquired a Kaypro 4
this weekend (just ~25 USD) - its in a bad visual state, but it
seems to work (I cleand it, and it is powering up), but there where
no system or application disks. So geting the system disks would
be helpfull. Do you have some, ode do you know someone who does ?
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,
