I would be very curious to look at your 6-bit instruction set. 64 instructions spread across how many general-purpose registers? Maybe 4 at the most plus you may need specialized instructions for process control and housekeeping tasks.
Yeah. The project currently has a CoC, so I'm not sure how interesting it would be to the 8Chan crowd. You might want to look at Chuck Moore's F21 & F32 CPUs. They were stack-based machines, so you didn't get any GP registers, just instructions that operated on the top of the stack. I got a kick out of his moniker: "Minimum Instruction Set Computer (MISC)"
