Kaypro ROM and CP/M versions and revisions

I would like to start the part 1 of the series on the Kaypro with an overview of the different ROM revisions and the associated CP/M versions. Most of the information comes directly from the Kaypro technical manual (1484-F, 1985).

I myself have two Kaypro 10/83 (81-180 / 81-277A / 1.9E(F)) and use different CP/M versions:

  1. KAYPRO 60K CP/M Version 2.2H ... => (EN) version
  2. KAYPRO CP/M 2.2 (GMv3.20K10F) .. => (DE) version
    • GMv3.20K10F = GM v3.20 K10 F
    • F = 2.2F ?

There is also an other german K10 CP/M 2.2 version: GMv3.11K10H. Unfortunately I do not have this version, only the picture from the internet.
