A small Z80 computer. This was made for fun to learn the Z80 CPU better a long time ago.

Simple monitor program for editing memory and running code was written but not much more. I also seems to have lost all material for this one.

Features

  •  Z80 running on 1.8MHz
  •  8k EPROM 2764 (contained <1k monitor)
  •  8k RAM 6264
  •  Hex - keypad with some function keys
  •  ASCII LCD interface (HD44740)
  •  8255 PPI for I/O
  •  8253 PIT
  •  8-bit multi-channel A/D
