The objective is to make a Z80 based single board computer that is a step up from the old retro computers The general specifications which will change with design progress are 1) Slightly higher screen resolution perhaps 400x300 pixels and 16 to 256 colors 2) More MIPS based on a MHz Z80 (Z84C00) a 5 to 10 increase in speed. I'd chiefly like to run the CPU at the full 10MHz The CPU is only running at 2MHz as the graphical LCD is comparatively slow (requiring a 900nS read or write cycle) and slowing the CPU down was easier than building the state machine to insert Z80 wait states Current Hardware Specifications 10MHz Z80 CPU running at 2MHz 128×64 pixel.
