 ohh, yeh.  hmm... e.g. http://www.rdc.com.tw IAD-100HV or their next
version hmmm...

 do you know what?  i think that'd be brilliant.

 yehh :)

 ahh... i know someone who is good at assembly coding.  but a compiler
is good (even if sdcc) then you do just the bits that are reaallly
speed-critical.

 really?? as free software?  where! where!
