Some time ago I was buying part for some of my "retro" projects. Beside of elements I needed, I also bought some vintage parts, that were simply "interesting", but I had no idea what to do with them at the time. Among them was Motorola MC6802 microprocessor.
It uses system bus almost identical to the one implemented in MOS6502, so I decided slightly modify project of my 6502 computer, to make it use Motorola CPU instead.

It will be rather easy projects, as the new computer should be 100% compatible with existing peripheral boards. The most problematic part will be finding and porting some BASIC interpreter for 6800.
