I think you have deciide exactly *what* you want to program. If
you want to mess around with hardware, e.g. blinking an LED or driving
a LED display or something like that, or build a small controller such
as a thermostat or a hottub controller, then the best way to do that is
to buy an 80x51 series microcontroller. Those things are almost
completely self contained and have a little 8 bit microprocessor on them.
They can't run anything sophisticated but they're the best way to learn
how to program a processor. They are also extremely cheap, in the
$3-$15 range typically. And you can very easily breadboard them.
High-end chips like the ultrasparc, or intel, or amd.... those are very
complex cpus and frankly you are better off simply writing assembly
from inside a real operating system, like DragonFly (or any unix) and
running it that way, instead of on bare hardware.
