I am fascinated by old tech like this. It really makes computing seem "real" to me. That you had someone weaving ROM to capture the program just shows it's a bunch of 1s and 0s. Stuff like rope core memory and mercury delay line memory are just this fun intersection of mechanical and electrical.

- matheusmoreira 3y agoThere's this eletrical circuit schematic from a very old arcade game. The circuit literally encoded the graphics of the game. It was a 2D grid of wires with connections meaning 1 and bypasses meaning 0. You could see the shape of the thing on the circuit. I wish I could find it again. I've searched the internet many times but to no avail. Perhaps someone here will know.
- watmough 3y agoI know this. I’ll dig up the reference in the am. It’s diode rom graphics. Atari GranTrak 10 used it for graphics, but the then new rom chips for code/data. https://edfries.wordpress.com/2017/06/14/fixing-gran-trak-10/
- matheusmoreira 3y ago> diode rom graphics So nice to finally learn the term of art. https://www.retrogamedeconstructionzone.com/2020/01/graphics-in-arcade-games-1972-1977.html https://www.retrogamedeconstructionzone.com/2020/01/graphics... The Space Race game. Like a bitmap soldered onto the circuit, as the article points out. This isn't the one I had in mind but it's still an excellent example.
