> its obvious why x86 won - you could get the critical jobs done.
It is a bit less obvious, in fact.
Motorola never looked at 68k CPU's as a serious business, more like toying around with the CPU's all the time or looking at them as a less important spin-off of the main business. Their main sources of income were defence contracts (e.g. specialised or hardened microchips), microcontrollers, DSP's (which were pretty cool, by the way, – all implementing the Harvard architecture), memory chips (I think), radios and the field radio equipment and later mobiles.
They carried largely the same attitude to 88k RISC and PowerPC CPU lines (albeit trying to compete more seriously for a while), but ultimately failing to catch up and leading to the eventual PowerPC demise. After that failure, they spun off anything CPU, DSP and microcontroller related into Freescale, and the rest is now history.
