I was trying to confirm a couple of points about the 3-D glasses on the Wiki, but can't edit the page. I can bring up the editor for other pages, so I'm not sure what's going on, but here's the content anyway:

Software interface
The low bit of the byte written determines which lens is active - zero to have the right shutter open, left shutter closed; one to have the left shutter open, right shutter closed. [I think it makes more sense to talk about which shutter is open, not which is closed, as you are writing code to present data to a particular eye].

Physical interface
The 3D glasses connect via a 3.5mm stereo "jack plug", as found on most headphones. The sleeve is common, the ring is the right shutter and the tip is the left shutter. [The LCD shutters are driven by AC, so I don't think GND is appropriate; it would be nice for someone to confirm the voltage and frequency generated by the Master System].

I'm not sure what happened there; I removed an edit password from the page so it ought to work now. I edited in your contributions.

Many thanks. :-)
