 alright, awesome.  i've got 5 very-very-first jz4775 cpu cards in
assembly at the moment (delayed by the xmas rush),

 microcontrollers are actually a very small amount of memory, so if
you are writing lots of code, you're doing something badly, badly
wrong.  it is however a bit of a mind-bender: everything has to be
state-driven.  it's single-process (no threads, no state-swapping),
interrupts and DMA.  so everything is done as a huuuuge
state-machine... or on polling with sleep loops.
