From the project
A Z80-based computer for nostalgic enthusiasts. With video output!
For starters, this is no more than a hobby project: a Z80-based computer. By no means it aims to be a practical solution to anything, as any modern microcontroller can do much better with lower cost, lower complexity, lower power consumption and much more ease of use. You can eventually make changes on it to perform some practical automation tasks and it WILL work, it's just not recommended nowadays. Get a PIC or Arduino instead.
