This page will detail retrofitting new electronics into an Atari Lynx V.1 The Lynx was the first RetroPie I completed, but for some reason, a project I have not documented. The Lynx was from my childhood, my brother bought it new in 1989. The Lynx is my favorite video game console. I still have 2 working Lynx 2 units and 55 games. This Lynx, however, was quite dead with extensive water damage.
The first version started with a backup camera LCD. Over the last 2 years, I have upgraded the battery and changed how you turn the unit off and on.
The feature that was a little disappointing was the LCD. It used composite signals, but really lacked the clarity and razor sharp display. The colors were a little muted as well. There were many SPI based 3.5 inch LCD out there, but the performance is disappointing. Finally, 2 years later, in 2017, a 3.5 inch HDMI display was being produced at a reasonable price.
