- TheOtherHobbes 2y agoPong doesn't have an ALU. The image and scoring emerge directly a forest of logic gates - mostly by timers and counters that scan the display, read the input controllers, and trigger logic events at various points in the scan cycle. Memory used to be ridiculously expensive, and it was cheaper to build a board full of dedicated logic than a simple CPU with a full-screen frame buffer.
