The original Macintosh project overlapped development of the Apple Lisa. In 1979 a prototype Mac board used a 6809 CPU because Apple wanted a system that could calculate in 16-bit. The Lisa project was using a 68000 CPU. A 68000 CPU could be used with all 16-bit components but the Lisa was using 24-bit and 32-bit components (for reasons) making it expensive. The Macintosh was supposed to be low-cost. The 6809 didn't need all those external 32-bit, 24-bit, or even many 16-bit components as it was technically an 8-bit CPU even though it could do 16-bit operations with 16-bit registers. However, Burrell Smith came up with a "bus-transformer" idea that let them use 8-bit components with a 68000. This allowed his graphics designed for the Lisa to run 60% faster on the Mac; speed, not cost, being his motive yet the design decreased cost as well.

Mac OS X and Mac OS Classic are individual platforms. However, games are still tagged Mac OS X and Mac OS Classic as needed due to the multitude of officially supported options to run the same application on both systems.
