I just hooked up my beige g3 again, and I can't get any video out of it! It makes the startup bong, it sends some sort of signal to the monitor, but no video is produced. I have tried zapping the pram, a cuda reset, having no ide devices hooked up, everything. Anyone have any suggestons? Did I miss something?

Try booting from a CD and see if the video comes up.
Did you check the pram battery? If it's very low, or dead, it may prevent the Mac from starting up past that point.
If my beige is anything to go by a flat/low CUDA battery shouldn't keep it from booting
One possibility is that the monitor can't display the signal being sentby the beige. You could try hooking up a different monitor and see if you have any joy with that.
BTW, Have you had it workning in the past or not?

Do a warm reboot 3-5 times. Let the machine bong, then give it about 20sec then control-command-power. Repeat the process 3-5 times, or until you get video. If after 8 or so tries you don't get video, it's not going to work, and you'll have to investigate other potential causes. It's kinda like the PizzaBoxPowerToggle used on the Pizza-Box LC's to get video on a machine with a flat PRAM battery.

I have a beige G3 MT, 333Mhz, 192ram and twin turbo video card (8megs vram) I bought this machine with this problem (Cheap,Cheap) and I have come to the conclusion that the rom chip is going bad (ver#.82.1) as the pram battery is new a hard reset (option/command +p&r) will after 4 bongs bring the computer up although at times it will show no hard drive.
I three of these machines and two of them work flawlessly. One using OS 9.2.1, the other OS X 10.2.8 and the problem machine running OS X 10.2. once it starts up it runs ok no problem but shut it down for 8 hours and you are back with the same problem. No Video at boot either from the onboard (ATI 6meg Vram) or the Twin turbo 8meg Vram PCI card.
I did not mean to be so long winded on this subject but I sincerly think the rom chip is going bad and replacing it with a later ver chip could be the cure. I have seen them for sale on E-bay at very reasonable prices.
BTW a dead pram battery will cause the same problem you are experiancing however if its good then go with the rom chip
