Description: Published 7 months ago

A complete mini Z80 system with 64kB RAM, Basic and Forth interpreters, CP/M, QP/M, Assembler and C toolchains, Serial port, User led and key that you can easily build on breadboard.

ROM/EPROM programmers are not needed because it is all stored inside an Atmega32A with the Arduino bootloader. You need only to flash the Arduino bootloader at first, then use the Arduino IDE to load the provided sketch).
