I bought some books about 8080 hardware and started with a photocopy of the motherboard so I could highlight the chips and the conductive traces I had identified. But I never took pictures of the process and the notebook is long gone. I went into programming instead, was proud to have created the first film sequence of a ray-traced glass ball smoothly moving on a checker board on a 8088 because I invented run length encoding, not knowing that this was a standard algorithm for the rest of the world.
