The earlier Sega machine (forgot its name) used the Z80.  The 68000 was put in
the Genesis so that it could be called 16-bit and better performance could be
attained.  The Z80 was left in there so that games for the earlier machine
would be compatible.  The Yamaha chip is the video chip I think.  If you give
me the number off the top, I can be sure.  The computer I am using has a
Yamaha video chip in it, and I know how it works.
