About this video
This is an 8 bit CPU/Minicomputer that I designed and constructed from scratch, using 74HC logic IC's. It is a Turing complete computer, meaning it has all the instructions necessary to compute any mathematical function. It had both audio and video generator circuits. It might look like there were lots of parasitics in there and that's true, but I terminated the edge sensitive signals.
In this short video, I programmed the computer to play a piece of the classic super mario bros song. The music was programmed by sending notes to the audio circuit including null notes to create the music tempo.
