Title: Commodore 2000 external keyboard
Post by: sixty on Fri, 09 October 2009, 00:34:40

Can anyone tell me what switches or technology this one uses?
To me it looks just like a Model F AT... is it? Or did they just clone the design.

Any help is appreciated, thanks.

Looks like the keyboard from the Commodore PC-1, a small form factor PC/XT clone. I bet it's just a regular rubber domes over membrane.

As far as I know, in its last decade (1984-1994), Commodore made a very little amount of mechanical keyboards, using Cherry switches. The Amiga 1000 and the early Amiga 2000A are an example.

The AT Model F's layout and physical appearance was often imitated, the capacitive buckling springs were never copied though.
