The Z80, 180, and 380 processor families represent three generations of upward-compatible µPs. The Z80 includes 150 instructions, many of which have numerous variants for operand location and ...

We see a lot of retrocomputing projects here at Hackaday that take devices from the 8-bit era and re-create them in the 21st century. Sometimes they remain period-accurate and stick to all ...

If you buy WS2812s under the Adafruit NeoPixel brand, you’ll receive the advice that “An 8 MHz processor” is required to drive them. “Challenge Accepted!“, says [ShielaDixon], and proceeded to first ...

The project aims to emulate an old good Z80 machine on an AVR ATmega88 microcontroller to be able to run software that has to be CP/M machine emulated. A Turing-complete device with enough storage is ...
