[G4] G4 startup problems

[Larry Parsons]

First of all I would like to thank all of you that have responded to my 
previous posts regarding my problems with my gigabit internet G4.
After replacing powersupply, logic board, & checking ram I finally got the 
machine to come to life.
The only thing is that it will not powerup from the button on the case and I 
must use a keyboard from an older unit to turn it on, seeing as how the 
keyboard that came with it does not have a power button on it.
So, I was wondering if anyone out there happen to have an old Mac like mine 
that they are parting out and could stand to part with the power 
button/board.  I've been searching on ebay and have not found a listing for 
one.  I'm not sure what models would interchange.  The Mac store I usually 
deal with is of little help.
