- 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.
