The Totally Accurate Controller MK2 (TAC-2) is an Atari 2600-compatible digital joystick game controller. It was commonly used with 1980s microcomputers such as the TI-99/4A, Atari 8-bit computers, Atari ST, Commodore 64 and Amiga. It was manufactured by Suncom in Illinois.
The joystick's square base came in two colours, black or creamy white. [1] [2]
It had a list price of $19.95 when it was introduced.[3]
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]
