abstract:The Microvision was the very first handheld game console that used interchangeable cartridges. It was released by the Milton Bradley Company in November .
Microvision's current pico projection engine uses red and blue laser diodes and a frequency-doubled "synthetic" green laser to create a full color image.
The combination of smaller size, lower power, and lower cost make direct green lasers an attractive alternative to synthetic green lasers for Microvision's mobile display solutions.
The 75x64 LCD screen was a big step up from the Microvision but, as you can tell from the number of people who have actually ever heard of the device, it never caught on.
