Z80 on a breadboard! Creating a "homebrew computer" using the Zilog Z80 processor. This is the most simple "test circuit" to ensure the chip actually works (many Z80 chips are actually recovered from recycled machines from the 1980s!).
In future parts we will make an actual useful retro computing machine and I will share schematics. This is the bare-bones to power up and see that it is operational.
