It changes the amount of pin and key range. I've seen this before somewhere, I believe it was used for curved screens or simulator use.

Is this also what an ultra board looks like? I have never been graced by the presence of a Marquee Ultra

Yes, that's for use in projectors that are to be used in a dome. It extends the range of adjustment of foucs and geometry.

Do those dip switches on top shut it off? You may want to PM Scott (TSE), and he can give you some good direction.

I had a FGM with that box, I took it off because the customers machine was having wierd problems, unsteady (shaking) picture, etc. not sure this was the cause but it's better to take off non-factory add-on crap if you don't need it.

They're not new. They have to be built from existing Kanto-Denshi focus yokes, which must have at least a 9 pin connector on them if they're to be in a Marquee 8500 or 9500. The adaptation of them to being ideal for a Marquee requires
rewinding the internal coils and changing the magnetic strength so that it is optimized for the Marquee focus system.
I will not be able to remagnetize the original Thomson yokes due to size limitations on the toroid I'm using. I wasn't able to get the toroid I really wanted. Some jackass beat me to it and is probably using it for a doorstop. The K-D yoke magnets
will JUST fit. The Thomson system is too large in diameter.
It'll be at least a few more weeks before my remag rig is set up and tested. I've also got to get a gauss meter.
Fortunately, the fixtures I need are something I can make for myself.
