Can't Get into Open Firmware

Question

Hi there,
I've got a G3 All-in-One and I can't seem to get into Open firmware properly. I've got the right combination (Option-Apple-O-F) but the screen just goes black. I've tried this on two different units and they do the same thing. Am I missing something?
Thanks in advance...

every once in a wile mine does the same thing. but it really is at open firmware its just the screen is so dark you can barly see anything even in a room at night with all the lights out. try doing it in a very dark room and look real close to the screen.try resetting pram first to see if that helps and then try to go into open firmware. I have 2 beige G3 AIO's both do this try to hold the key combo as soon as you start to hear the start chime, then if this dont work try to hold them just after the start chime, and try to hold them at diffrent length's of time first start by trying to jusk keeping the key combo held down, then try realeasing then just after start chime, one of these combo holds should work. but make shure you are in a room that will be dark with the light's turned out cause very faintly you should see the open firmware prompt at the very top left of the screen.
good luck
