The Motorola 68k series. A very nice 32-bit architecture that was fun to program. The downside, Motorola isn't making new ones, and I'm not sure who owns the property. Another nice 32-bit architecture was the VAX. It had the most regular assembly language I've ever seen, despite being a CISC architecture. But sadly, both are obsolete these days.

- spc476 3y agoOh God! It sounds dreadful to program on a ColdFire CPU. Some instructions I agree (CALLM), but the ROL/ROR instructions? ADD only applies to long words? Insane.
