Does anyone see any problem with doing this? I know that the multilink adapter box is good at translating vga signals, but do you think it will work. I have the proper 13w3 adapter to attach to the monitor cable to make it VGA, but I do not want to damage my SGI flatpanel in the process.
Thanks,
Chef
I don't think you'd damage it, but does that monitor support SOG?. You might need to make a sync seperator using a Nat Semi LM1881 IC.
I am not sure. This page on SGI.com says that "There is no support for the Sun timing mode in the MultiLink adapter box". Does Sun do composite sync or SOG.

Sun does seperate sync I think, it may also so c-sync (which is the two signals combined and the same thing that's combined with green on the NeXT)
Not sure but I think some Sun graphics adaptors (Creator 3d) might also have SOG. You usually find that if a monitor requires seperate sync, the job can be done by attaching c sync from the video out to h sync on the monitor, at best it'll ignore the v sync that in there at worst it just won't work, the best bet is make an LM1881 adaptor, it's easy if you can solder and costs about 4 bucks.
I have tried this set-up on Dimensions and Color Slabs and it does NOT work.

Thanks for the clarification. I was hoping someone else had tried this.

I think if you consider the fact that in essence the multi link is virtually an SVGA monitor (without a screen, which is what the 1600SW does) in itself which does not support SOG, then it become apparent that if you made up a SOG seperator circuit, that logically if that adaptor worked on a normal SVGA monitor that does not support SOG, then it should also work with the multi link, as long as the resolutions/timing are supported by the 1600SW.
For the sake of 4 bucks, it's at least worth having a go. Can you solder?

Depends on how neat it has to be. I have replaced ends on cables, or made simple "circuits" with wire and 9v batteries to put LED lamps in bottles, but that is about it.

Well I used a Belkin SVGA extender, cut the end off I didn't need and then soldered a 13w3 on the the RGB wires, the LM1881 is so small it fits in the shell. I had to run a Molex Y cable out one of the holes at the back with ground & 5v to power the IC. I used female and male phono jack so I can unplug if I want. Works great with the horrible beige CTX monitor I borrowed from work. Does not work with the POS Viewsonic VP171-b I have, god damn thing, what pisses me off is that somebody else on the old forum had a VP171b working on a slab. Sure the damn thing works on my cube but I can't remember as I have a Viewsonic at home in UK as well.
There is a thread I started the tells you how I made it. Took about an hour, using the docs of Nat Semi's website. You need a couple of caps and a couple of resistors as well.
