  • Obstacle Runner
  • enhanced Hex Invaders game
  • The Lighthouse text adventure
  • enhanced Haunted House text adventure

So many Z80 projects and always so little time...
reZet80 stands for "Reset me back to the 80s with the Z80".
reZet80 features a set of retro projects to develop computing and arcade systems that resemble the Z80 machines of the late 70s and 80s.
All systems are built from scratch and not copies of any other Z80 system.
The development process includes hardware design and software programming in Assembler.
I started reZet80 back in 2016.

Off-topic note: The letter Z stands for the company Zilog and the Z80 CPU. The Z is in NO WAY related to the Russian war against Ukraine!
