No update photos yet, but I had to make a few modifications to the clock design, as the earlier version had a race condition. I've had difficulties making it possible to change direction while incrementing the 74HC193 without glitching, so I split the clock into one that's consumed by the Instruction Pointer (IP), and another that's consumed by the rest of the logic. I'll go into more detail in the next update, which should come in tonight or tomorrow.
