A few days ago I was researching some of my old video games and one of them is the Microvision by Milton Bradley. It turns out that this is the world’s first handheld video game console with interchangeable game cartridges. It preceded the Game Boy by 10 years. I have 3 of the 11 games that were available. The system was introduced in 1979 and I purchased mine in 1980, 38 years ago. The liquid crystal display has a resolution of 16X16 pixels.
