Atari 800 Mitsumi keyboard
This keyboard, tentatively Mitsumi KSD Type, is unusual in having two membrane sheets over a PCB, instead of the usual one or three. Additionally, the sliders are cruciform mount instead of the standard negative square Mitsumi mount. The PCB and outer membrane sheet are both marked with model KSD-A58AU.
The four keys on the right of the keyboard use switches attached to the power board. In the example below, these appear to be Stackpole discrete switches: the position of the locating peg and the terminals is correct. These four keys can also use a presently unrecognised switch type, found in a keyboard with a Stackpole keyboard assembly.[3]
The keyboard module is dated December 1982.
