Hi,

I guess the best solution is a PIC with embedded UART. U may use e. g. 
PORTB (pulled up weakly which is an option) to handle the buttons and send 
a character assigned to each individual button. Even an F648 may be 
sufficient, if no other peripherials needed. The program size remains 
below 0,5kw I guess. Even the power could be drawn from the serial port so 
no external battery or such is required.

Regards,
Imre

That is, rewind,stop,play,fast forward and 3 or more spares for doing other things. Has anyone seen anything like this available? The end use would be to connect it to a PC and use software to determine what buttons were pressed and do things accordingly.
