- Tandy Radio Shack Computerized Arcade (1981, 1982, 1995)
- * TMS1100 CD7282SL
-
- This handheld contains 12 minigames. It looks and plays like "Fabulous Fred"
- by the Japanese company Mego Corp. in 1980, which in turn is a mix of Merlin
- and Simon. Unlike Merlin and Simon, spin-offs like these were not successful.
- There were releases with and without the prefix "Tandy-12", I don't know
- which name was more common. Also not worth noting is that it needed five
- batteries; 4 C-cells and a 9-volt.
-
- Some of the games require accessories included with the toy (eg. the Baseball
- game is played with a board representing the playing field). To start a game,
- hold the [SELECT] button, then press [START] when the game button lights up.
- As always, refer to the official manual for more information.
-
- See below at the input defs for a list of the games.
