OSNews, Generic OSes GEOS managed to offer nearly all the functionality of the original Mac in a 1 MHz computer with 64 Kilobytes of RAM. It wasn't an OS written to run on a generic x86 chip on a moving hardware platform. It was written using immense knowledge of the hardware and the tricks one could use to maximise speed. Note: After a small break, here is another one of the articles for the Alternative OS contest.

The Macintosh mutations that used the Motorola 68000 were not truly 32 bit processors: they had a 24 bit address bus, a 16 bit data bus, and also did have some instructions that would work on 32 bit data, but... they were not truly 32 bit processors. Were they better than the 8088/8086 available then? Most certainly! For a given clock speed (and the Macintosh started at about 8 Mhz) it was more efficient per clock cycle, and it also had more registers, but it still wasn't a true 32 bit chip.

Other than that, it was a great article.
