Did you ever wonder why the popular early PC's (Apple, Acorn, Atari, and Commodore) and
video games (Atari, Commodore, and Nintendo) were built on 65xx technology rather than on
Intel x86 or Motorola/Freescale 68K technology?
Take a look at the 65xx 8-bit and 8/16-bit microprocessor execution speeds on an 8-bit data
bus in the table below compared to the Intel x86 and Motorola MC68000. Now you know! Also,
the performance of the x86 and the 68K were on a 16-bit data bus! The PC (x86) and Mac (68K)
ran less than 8MHz memory bus speed when first introduced.
