The Microvision was introduced by Milton Bradley in 1979, and was the first handheld game console to use interchangeable cartridges.
The main unit was little more than a housing for the display, batteries, switches and controller, while the brains of each game was a combined microprocessor/memory chip inside the clip-on cartridge. This enabled the use of different processors depending on the complexity of the game. Each cartridge contained 2 KB ROM and 16 bytes of RAM.
The cartridges were susceptible to damage from static discharge.
Only 13 cartridges were released during its life, and along with its small screen, this helped lead to its demise in 1981.
