Great tiny tapeout project; hopefully this will result in drop-in replacement Z80 parts for vintage machines as well as new designs and homebrew systems for CP/M etc. Then there is the MCLZ8, a cycle-accurate emulator that runs on a microcontroller (which itself is much more powerful than the original Z80) based board that can plug into a hardware Z80 socket: https://microcorelabs.com/2022/05/11/mclz8-zilog-z80-emulato...
