Re: Re(fcc): TI-H: Radio/Infrared/Laser Communications
there's a fun idear...an AVR based PC...possibly multi-avr because i don't
think you could reasonably handle an keyboard, ISA video board, and HD on
one chip :> (mostly an issue of pin space, and doing multiple things with on
pin in that kind of a situation would slow things down too much). gotta
admit, it would be pretty cool, no? Hell...program one central chip to
emulate the M68K or 80x86 instruction set just for fun (not sure how much
code space the AVR's have, i haven't looked at their data sheets) :>
