Microvision



The Microvision is a early handheld console made by Milton Bradley, notable for being the very first handheld to use cartridges. The cartridges were actually the frontal part of the console, and each one came with it's own LCD screen and set of buttons. Unfortunately it didn't receive much support and was prone to failures, so despite a relative success it died fast, just before the Great Crash. Only twelve games were ever made for it.
