The Suzy ASIC (Atari Lynx II)

the suzy chip is one of two asics on the atari lynx ii the console will not operate at all without both chips present the suzy is clearly responsible for the button presses on the console based on the schematic however, one thing i discovered through a broken atari lynx ii was the suzy is actually responsible for generating the pixel data the hayato drives the lcd , however the exact pixel data it sends to the screen comes from the suzy chip so the suzy chip also handles video data construction
