This is not an exact replica like the one linked above, but an
ingenious DIY re-creation built with modern parts, including just two ICs, with an ATMega8 processor instead of a Z80.
Not an emulation, but a complete rewrite of the original Z80 monitor and BASIC interpreter in AVR assembly.
- musicale 2y agoI am reminded of these drop-in replacements for a hardware CPU, implemented in software on the Teensy microcontroller platform: https://microcorelabs.wordpress.com https://microcorelabs.wordpress.com Cycle-accurate emulation with appropriate electrical connections and pinout make it a fully compatible software implementation of the original hardware CPU.
