Several video game consoles from back in the day (the Magnavox Odyssey 2 and Entex Adventurevision) used the MCS-48 microcontroller mentioned in this write up instead of more conventional CPUs of the time like the 6502 or Z80, which seems a bit strange. Having dabbled in both MCS-48 and 6502 assembly I can tell you it was probably not done to make software development easier. :) I suspect maybe the hardware was just easier to design around a microcontroller? ...but there could have been other reasons...
