AVR-Chat

Answers to your questions:

1.  Yes, you can make these chips comply.  The question now is, how much 
will it cost you.  It's only a matter of the depth of your pockets.

2.  With wire and solder.  Wire wrap if you prefer.  You can use a UART, 
USART, or just plain old gas.

3.  Their names, for starters.
