Runnet CPU: A Processor You Can Step Through

Field notes

Runnet describes an RN-8 processor built from 2,161 NAND gates and 167 flip-flops, with sixteen registers, 256 bytes of RAM, and thirty-two opcodes. The browser interface exposes stepping, reset, input, output, program-counter, and gate-switching state rather than presenting a pre-rendered animation. The page says its gate table is also used by a Solana program, where each transaction advances one clock edge, although the extracted view shows no connected wallet or live chain readout.
