Kept on Wikipedia:TAC-2
The Totally Accurate Controller MK2 (TAC-2), manufactured by Suncom Technologies, is an Atari 2600 compatible digital joystick, commonly used with the Commodore 64, Amiga and Atari ST computers in the mid to late 1980s.
US-made model
The joystick's square base came in two colours, black or cream. [1]
Features
- One 8-way stick (4 digital switches)
- Two fire buttons (wired in parallel as button 1; indistinguishable in software)
Construction
- The joystick has no microswitches. Instead, it uses a metal ball that short-circuits contacts around the bottom shaft of the controller.
- The handle has a customized tyre valve (TR-418) of rubber for self-centering. The handle is covered with a chrome sleeve.[1][2]
- The fire button switches are brass contact plates which tend to become corroded and thus need care every now and then.
China-made model
A cost reduced version was released, in which the tyre valve was replaced with a white rubber gasket that held a black plastic tube. The metal ball was only plugged into it (not screwed in as the original version), and the brass plates in the buttons were replaced with the wire of the redesigned button return spring.
It is only known in black and can be recognized by its shiny plastic stick instead of the chrome valve sleeve, and deeper red buttons instead of the original orange.[1]
