I have built several projects  for a ti calculator based around a PIC  ...
however I always had to buy the PIC's pre programed beacaus ethe creators
would not release the code..  I do not know enough about asm yet to even
begin to atempt this .. but it sure would be a cool project for anyone that
had the skills to do so.

I have heard many many people ask about comunication between a stamp and a
ti-calc on the stamp list, but have not heard anything on this list yet.

to anyone interested I have a few url's which I found very interesting...
about Ti-link protocal and such

http://www.geocities.com/SiliconValley/3061/index.html
here there are text files dealing with the link protocal

here are some of the projects which use pics...
