Well I sprung for a mac keyboard. It is an ugly apple pro keyboard v 1.22 that feels like someone soaked i in bleach to get it clean. After pulling keys and putting them in the right locations I hooked it up and was able to boot the yikes board into open firmware with the original G4 400 MHZ Processor and I can Get the three chimes when I hold down the cmd opt PR.
Putting the 500 Mhz Processor in the slot I was not able to get the dual or thrice chimes when holding down the cmd-opt PR nor was I able to boot this into Open Firmware. Still No video on boot-up. Just the one chime. I can only conclude that this PPC G4 is no good. Any last idea's now that I have the keyboard? Thanks for all that contributed. Gus.
