You should take a loop at the Parallax Propeller. It has 8 realtime
cores and each run at 80MHz . 32 I/O pins and prewritten objects for
many motor control applications. To top it off, it has built in VGA
video drivers so you can connect a monitor, mouse and keyboard. A
prototype board runs about $30. You can program it in Assembly, SPIN, or
C, But I would recommend trying out SPIN. If you know C SPIN is pretty
easy. There is a free 3-Party compiler know as BST. It runs on Macs,
Linus, and PCs.
Take a look at the Sticky Notes at the top of the forum at:

I have used PICs, AVRs, and others. Compared, the propeller is an
awesome chip. -Chuck-
