Smallest Binary CPU Bedrock Edition

I got inspired by The Darkness344 who made a 30x30x30 4 bit cpu and N00b-asaurus* who made the 40x40x40 4 bit cpu and started the smallest binary cpu trend.

I made a 21x21x21 8 bit cpu, pistonless, observerless and command blockless. It was, perhaps clearly supposed to be 20^3, but this shows I can’t count.

Obviously there were sacrifices, as the ALU can only do add/subtract and the RAM** is only 2 cells, each 8 bits.

It runs on a 13 redstone tick clock, or 0.769230bar Hz

If you use parts of the cpu in your creations leave credit to me.

Unfortunately, I had to use Bennyscube’s adder, as mine took up to much room

NOTE; not 100% debugged.

**At this point, it’s general purpose registers…
