I am having some difficulties with my Powermac 6100. It does the what the below says, and then it does nothing more.
It chimes, but goes no further. No video output (The CRT remains in standby)
I have fiddled around with the DIP-switch on the Mac-to-VGA adapter, but it does not make a difference.
Any clue on where I should start? RAM maybe?

yes, I will remove it and see what happens. I did not try that. My mistake 
Edit: I found a spare PRAM battery that I saved from a dead eMac a few years ago. Succes, it booted right up
See the picture below. It's running 7.5

I've also got issues also with a 6100/66 DOS compatible.
Its missing one its feet, but that is the least of the problems.
I put in an old pram battery and press the on off button several times to get the juice to the monitor.
It boots with the Stanley Jordan chord and its loading 7.6.1 and then this static noise through the speaker.
I have removed the DOS compatible card (it got really hot) and the monitor is running off the built in video.
Any clue as to why its making this hideous hiss?

It could be a capacitor maybe? Also, where does the DOS card get hot? On the CPU heatsink?

the only way i can get a 6100 with a dead PRAM battery to boot is to press the power button on the machine itself, let it come on, then press it back off and back on real quick like.
boots every time.

Mine does the exact same thing, and it hasn't had a PRAM battery for about 5 years now

its been since 1999 when i had my 6100. it was my VERY first owned powerPC mac, and even then, thats how i had to start her up. because of a bad PRAM batt.
its been long since gone. but it was fun.
My second owned PPC macintosh was a "hackintosh 5400" Basically, the analog board we bad. shorted HOT, bad flyback.
So i completely gutted the machine, and cut the plug going to the secondary power supply. I wired up an old AT style power supply into the wires running to the 5400 system board.
it worked great, i had to tap a VGA monitor into the video wiring off the logic board connector as well. It had some ghosting because of impedance mismatching in the wires, but it worked.
I had that thing until eventually i ended up with a performa 6200 which took the same type of logic boards.
