Wizard Electronic Game

Rev A October 2019

Handheld Electronic Game

• ATmega328P microcontroller running at 12MHz
• 10 push buttons with red LEDs
• 4 buttons for game mode
• Buzzer
• Tag-Connect for programming
• Runs on 3 AAA batteries

The microcontroller runs a TMS1000-series emulator I made.

Two ROMs are loaded on the emulator: Merlin (TMS1100) and Master Merlin (TMS1400) (by Parker Brothers).

By default the game boots in Merlin mode. To play Master Merlin, press any of the four mode buttons while turning on the console.
