Is there anything special about this cable does it pass any other signals except for video (I'm thinking about the brightness controls on the keyboard here).

Mines a bit dodgy and I was wondering if I could use an SGI one, as they are plentiful, I have one I can try off my Octane but I'd rather not fry anything.

It's just a standard 13W3 cable; in fact it doesn't use any of the other pins besides the three video mini-coax, since it uses Sync-on-Green.

The keyboard plugs into either a sound box or a mono monitor, and doesn't come anywhere near the Dimension board.  Unlike on the color slabs, you don't need a Y-cable for the sound box on a Cube -- use a normal mono video cable from the Cube motherboard to the sound box, and a 13W3 cable from the Dimension to the color monitor.

The brightness control is done in software (although the color monitors do have brightness and contrast knobs on them too); the only "special" key on the keyboard is the Power key, which has its own pin in the connector.  All other keys are handled normally by the keyboard controller.

Hi thanks

So basically if I plug my SGI 13w3 into the cube and then into the montor I ain't going to fry the dimension, thats cool, I could'nt see that it would but I thought caution was best as dimensions cost quite a bit over here.

If nothing goes on inside the monitor except it displays a picture and brightness is done in SW, then why are there ADB and Non ADB version of the color monitors?

I believe the ADB monitors just supported a higher refresh rate -- 72Hz vs. 68Hz.  Obviously the mono monitors also had different versions of the audio and keyboard/mouse functionality, as did the sound boxes, and the sound box cable, and of course the keyboard and mouse.

IIRC, the NeXT Dimension 13W3 cable does not have any other pins besides the three mini-coax (I'd have to go bug my father to find out for sure, but regardless of whether they are present in the cable, they are not used for the video signal), so if you are super-paranoid you could break off the 10 little pins on the NeXT end of your 13W3 cable.  It's probably not necessary though.

I have a 21" Hitachi/NeXT and it seems to work fine with both my Turbo Color Slab (72hz AFAIK) and the Dimension which is 68hz, why did they change the monitor, from what I read, old and new monitors alike are able to sync to 68 or 72hz with no problems.

AFAIK, only Turbo Color Slabs where 72hz anyway, is that correct?
