I was wondering why there was so many postings on a usually quiet
list....

I'd be interested in the PCB board too..

I understand that some AVR's have a built-in USB interface (perhaps
wiser to say - AVR's that have some form of USB knowledge). I also lurk
on one of the AVR mailing lists - GCC will cross-compile for the AVR,
and you can use C++ - etc.. as well. I have a STK-500 (AVR) development
kit and followed examples with the avrlibc projects - one of the
examples includes a 4-bit interface to the HD44780 - which works fine.

Actually had to use the LCD4Linux projects to get the pinouts for the
HD44780 to play with the AVR demo's...

Be nice if the PCB board also had a GPIO (or two) and (say) 4 buttons
for input  :-) .... ie - like the picture of the Blade server
(http://ssl.bulix.org/projects/lcd4linux/wiki/CoolStuff)
