An Unlikely Host For An 8080 Emulator

Ted Fried built an Intel 8080 emulator running on an ATtiny85 microcontroller, a device with very limited pins and processing power. The project offloads support functions to a Teensy via SPI, uses heavily optimized C code, and includes a 128-byte cache. Despite the constraints, it runs CP/M at near-real 8080 speed. The full write-up, complete with fake 1975 electronics magazine covers, and the source code are publicly available on GitHub.
