The Microvision is a handheld game console released by Milton Bradley in 1979. It holds the distinction of being the first handheld system with interchangeable cartridges, allowing users to play multiple games on a single device.
The unit featured a 16 × 16 pixel LCD screen and used a combination of cartridge-specific hardware and overlays for control inputs. Each cartridge contained its own microprocessor, as the console itself had limited internal computing power. The initial processor used was the Intel 8021, later replaced by the Texas Instruments TMS1100 in some models.
Games were inserted as large cartridges that slid over the top of the unit, including the screen and controls. Notable titles included Block Buster, Bowling, and Star Trek: Phaser Strike. Despite its innovation, the Microvision suffered from technical limitations such as screen rot, keypad failure, and a limited game library. |
