SpaceChem Applied Fusion with in-SpaceChem-Computer

I tried to build a simple computer, that reads commands and executes them, and this is what came out of it. So, in computer terms: It’s a harvard-architecture with a ring buffer as programm memory. It has 2 registers (the fusion reactor and the second sensor reactor) and knows 3 opcodes, all of which modify both registers. No, it’s not turing complete :-D Things to do better, but for which I basically had not the space: 1. Seperate outputting from register 2 (to fina
