Hello,

I've got a Power Mac G3 Beige (266) with a DB-15 display connection. Since I don't have any compatible display I'm trying to use my LCD VGA ( Acer B193 19'' 4:3 1280x1024 75Hz native resolution ).

I hear the startup chime and the hard disk, fans are running and the green led is lit, but I don't get any video signal.

I have a VGA <-> DB-15 adapter but it didn't work, tried all switches positions.

Also tried a PCI video card with VGA output ( Formac ProFormance III 16MB, especificaciones: http://www.xlr8yourmac.com/graphics/Proformance3/index6.html ) but no results.

Would other PCI video card work (like an ATI Radeon Mac edition)? Or the ProFormance should've worked? Should I get video signal even if I don't install drivers?

I did reset PRAM. Command + option + P + R didn't work so I had to remove the battery for 10 minutes to get the PRAM cleared, I also reset the CUDA chip.

Still not working.

Tested all RAM DIMMs one at a time, checked personality card... no results.

iMac G3 CRT has a DB-15 display, so I connected it to the PowerMac... no luck.

Should I try with a regular CRT display?

Any ideas please?

Thanks for your help!
