I didn't mean to imply that it had an extremely powerful instruction
set. I meant to imply that it was neater that the intel instruction set.
Every instruction has its own definite instruction with no mode or
register address bit values to calculate like with x86 instructions.
It's just a lot easier to write low-level code for than the x86 in some
respects. And besides, with the 32-bit z380, I imagine they've added
signifigant improvements to the instruction set. And by the way; I know
that laptops are out, but if the people on this list were out solely to
program laptops, they wouldn't be on this list now would they?
