indeed it was black - thanks so much for the tip Geoffrey!

All appears to be A OK now - though I am reminded of the need for regular back-ups!

That button is the CUDA reset kind of like a master PRAM reset

The Cuda is a microcontroller chip on the Power Macintosh G4 (PCI Graphics) logic board. Whenever you have a Power Macintosh G4 (PCI Graphics) computer that fails to power up, you should follow this procedure before replacing any modules. This article explains how to reset the Cuda chip on the Power Mac G4 (PCI Graphics).
