Yeah, you can get some different effects by having 8 connectors on the back, 4 from the board and 4 from the yoke, and cross patching the connections with only one set of speaker inputs. So you might have board connection 1 going to yoke input 3, board connector 3 going into yoke input 4 and the other two yoke inputs taken with a speaker input.
I have a couple of wobblevisions built like this (including a green screen and a blue screen monitor) but i'd never do this on anything i was going to sell as in my experience if you accidently plug the speaker inputs into the board connections or if you plug a board connection into another board connection, something is going to go up in smoke. Also, i had a couple of old amber screen monitors that just burnt out when i did a certain cross connection on a patchbay. Most CRT's seem to be alright with it but its a little risky.
That connector looks like a specialist one for this job, at least i don't think i've ever seen it on anything else.
My iMac (333mhz G3) screen shuts off when there is no signal. Sorry. Also, the cable is not a normal VGA cable, it is one of those annoying old Mac VGA things.. you need an adapter if you are going to plug the iMac into anything else. I suppose you could find a schematic somewhere of it and experiment with the pins yourself.

No signal from where?
If you open it up and physically detach the CRT tube deflection yoke from the main board but have both the tube and the board powered up the tube shuts down?
I'm not talking about any kind of external cabling or plugging it into anything else here. I'm talking about one of these.

Oh.. Sorry, I was thinking about the VGA signal for some reason. If the computer isn't attached to the screen, the screen shuts off. I wasn't talking about the deflection coil. And yeah, I have that machine, well the tray version but IIRC they are basically the same inside.
Cheers for all the info. Well that Dutch guy wobbled his compact Macs with 8 in/outs so I'll do it like that... kinda fancy the bars. No-ones gonna touch the patch bay but me so there will be no music going into the board oh no!
Looking forward to the X-mas-the-whole-world-goes-into-recess-I'm-in-the-house-circuit-bending break!
