In the Maker Shed: 4-Bit Microcomputer Kit
Features a 20-key keypad, a single 7-segment LED, and 7 individual LEDs, and comes with 7 bits of software built in: an organ (basic tone generator), sound hit game, whack-a-mole, tennis, timer, music player, and Morse code generator. It’s a fun, retro kit, just begging to be hacked!
