Yay! Have just successfully run this on my simulated logic gate CPU on my phone, at a whopping 1Hz! Machine code on left, address middle, then assembly code, then comments.

A bit work in progress but I've been gradually building/simulating a Ben Eater CPU (from logic gates) on my phone for a while and finally got to the bit where I get to decide on the instruction set. It's still subject to change but was fun coming up with it. Hoping I won't miss a LDV instruction!
Plan for a CPU instruction set with control word and up to four microcode steps for each instruction, as well as logic notes and instruction explanations.
