Sources
The information below is sourced from the following:
- Cherry Keyboards (Catalog No. KB79-2)
- Cherry Keyboards (Catalog No. KB79-2R, May 1982, USA)
- Cherry Keyboards and Switches Catalogue 1982 (Germany)
See Cherry catalogues on the Deskthority wiki for copies of this literature.
Still required
- Cherry Germany keyboard and switch catalogues for all years except 1982
- Any switch brochures that go into more detail than the catalogues
- Part number schemata
- Detailed literature, as the literature discovered to date makes little effort to explain the huge variety of features and configurations (many of which have never been seen)
Catalogue types
The following is the list of known types; most are from the 1982 German catalogue (1982/DE). The details are cited verbatim, although the column headings are simplified for space. The contact pairs column is added for convenience. Note that the M71 types have dual stems which, while being straight as noted, are not compatible with standard 12 mm keycaps.
Note that M73-0120 has NSN 5930-00-365-9194 and RS part number 338-765.
