[avr-gcc-list] PS2 mouse interface code

[al boehnlein]

I would like to read a  PS2 mouse with some data lines on the MEGA169 
butterfly.  I have found some old code for the 128, but the definitions are not 
compatible with the more recent versions of the GCC compiler, and it is not 
clear what registers he was using, and what he was doing with them.  It seems 
pretty hard to port it.  I think it would take days for me to understand how to 
setup all the registers correctly so that I have an efficient, bi-direction, 
interrupt driven code. Has anyone did this already?  This is for a handicap 
scooter project that I am working on for a friend who had a stroke.  Any help 
would be appreciated..
