I built a computer chip by chip and wire by wire after designing the
schematics for the system. It is designed around the ZiLOG Z80 processor which
runs at 4Mhz. The system memory is broken into 32KB of ROM and 32KB of RAM.
This computer wasn't designed as much for real use as it was for learning more
about computer architecture and digital electroncs.
I'll be posting the schematics at some point.
