Kaypro ROM Revisions and CP/M Versions

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) (en, 19 MByte).

I myself have the model 10/83 with the ROM version 1.9E(F) and use the CP/M version 2.2H. But! When I got my Kaypro, the CP/M version 2.2F was installed on the hard drive. The Kaypro ran but still fine! In principle, however, the CP/M version suitable for the ROM should always be installed.
