A. GENERAL
This part provides a general description of the 43 keyboards as components used in 42/43 Basic Terminals
(KSR and RO).
The 50K122/AAE and AAF unitized keyboards are a direct replacement for the 43K101/ CAA and CAB
modular keyboards respectively. Tlie distinctive aspect of this keyboard is the unitized construction and
normally open capacitive key elements in a matrix array.
All ordering numbers shown in this manual are Teletype Corporation part numbers. When ordering replace­
ment parts, unless otherwise specified, prefix each part number with the letters "TP" (ie, TP410055) .
B. KEYTOP ARRANGEMENTS
The keytop arrangements used in the 43 keyboards are divided into three major groups according to func­
tion or purpose. They are the operational controls, status indicators and the basic keyboard.
A description of the function of the keytops found-on the keyboards shown in Fig. 1 through 2 can be
found in the applicable How to Operate Manual or Service Manual.
