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 68000 was fully 32-bit internally. So, it wasn't just 'some instructions' that operated on 32-bit data, but most instructions since its general-purpose registers were all 32-bit.

Yes. It did have a 16-bit data bus and a 24-bit address range (the address bus was actually 23 bits wide - it took some extra magic to access odd addresses). Thus it was usually billed as a 16/32-bit CPU.
