Key Tronic product codes

The following are the label codes from various Key Tronic keyboards, sorted in order of model number.

Code identifiers (“S/N”, “K,E” etc) are left exactly as written on the labels. Due to the confusing date codes used, all dates are reduced to month and year, although even the month may not be correct if that is not what the codes really give.

The technology types are:

F+F/L
Foam and foil, linear
F+F/T
Foam and foil, tactile
RD
Rubber dome

The technology field is left blank where it is not directly observed, although in some cases it can be inferred.
