- Parker Bros Merlin handheld computer game, by Bob Doyle
- * TMS1100NLL MP3404A-N2 (has internal ROM)
-
- To start a game, press NEW GAME, followed by a number:
- 1: Tic-Tac-Toe
- 2: Music Machine
- 3: Echo
- 4: Blackjack 13
- 5: Magic Square
- 6: Mindbender
-
- Refer to the official manual for more information on the games.
-
-
- Other handhelds assumed to be on similar hardware:
- - Dr. Smith - by Tomy, released in Japan (basically a white version of Merlin,
- let's assume for now that the ROM contents is identical)
- - Master Merlin
