From the project
Discrete Integrated NISC Operator — an 8-bit CPU built from 74-series logic on breadboards. That's the machine itself: no microcontroller, no FPGA. Every register, every bus, every gate is a chip you can put a probe on. (The repo does carry a generated FPGA twin for design-ahead

Schematics in KiCad, microcode in EEPROM, and a bare-metal ATmega2560 test rig that brings the machine up one board at a time.
