Is this thread still going?!? And with the same "quality" argumentation too.
The 68k is obviously the better ISA compared to x86, more registers, flexibility, address modes, and a lot more. But the x86 isn't a bad ISA even in the pre-386 form.
Both 68k and x86 have architectural warts, bad extensions, quirks requiring extra hardware to execute fast and non-orthogonal parts.
Aren't there more relevant things to argue? Like what parts of each architecture would be worth preserving in a theoretical new design or if it will rain this date next year?
@roondar
That is a bad argument. At least a few years ago one could buy 8086 compatible ROHS chips and I found a 8088 compatible sold now with a simple search. Most known old IC designs are available from specialized producers of legacy chips.
