Thanks. I believe the power supply is fine, as the whole machine comes on and I get a good startup chime - which I think means that all the hardware checks have been passed successfully.
However, I get nothing on video at all. This is why I thought it might be the ROMs, because it doesn't get as far as looking on the disks for an OS. When I interact with the Open Firmware, that's over the serial port as the PCP has issues with driving the video board from OF.
I've had other broken machines in the past and it's generally been one thing or the other - no proper startup because of battery, processor card etc., or getting the cursor up and just not being able to find a boot disk. This is somewhere in between!

I'm new to the list but have had years of trouble-free service from my PowerCenter Pro 210. I've come up with a problem that I've never seen before and I thought maybe someone could shed some light on it - soluble or not!
The problem became apparent when I took the machine down after it had been switched on and running perfectly for about two years (as a server). I'd had a G3 upgrade in it that I wanted to try in another machine (it works), and when I put it all back together again it wouldn't boot from the Adaptec SCSI card that it came with.
So the power supply does spin up, right? If that's the case, then you
can rule out the NVRAM battery. I've always found power supplies capable
of the strangest things, myself. I've had more than one PC where it
would NOT turn on and only after leaving the machine alone for a few hours,
would it turn on and work. I've had similar wierdness with my PowerWave,
where it would boot (apparently) but there was nothing going to the
video. A hard reset cured it.
You can see video and it's just the blinking ? over the Mac icon over and over?
