What a time to be alive. Can you imagine a love child between the ZX Spectrum and a Commodore64? No? Wait, here you go.

The CERBERUS 2080™ comes equipped with two(!) CPUs out of the box - a ZX80 AND a 65C02!

This project of Bernardo Kastrup of The Byte Attic is a mind bender. Not only is it a real beauty from the outside, it was fully open sourced, well documented on github and featured on HACKADAY.

A multi processor system comes with a number of challenges. Thankfully Bernardo guides us through his thought and design process in very much detail in his dedicated Youtube series.
