An Unlikely Host For An 8080 Emulator

An ATtiny85 microcontroller hosts an 8080 emulator via SPI bus with a Teensy providing RAM, ROM, and floppy support. The code uses optimized C and a 128-byte cache to achieve near-real 8080 performance for CP/M booting. The project includes fake 1975 electronics magazine covers and is available on GitHub. Emulation speed is only slightly slower than a real 8080. The approach demonstrates efficient resource management in constrained hardware.
