I have built an interface that connects the Sega 3D-glasses (high speed liquid crystal shutters) to the Macintosh RS-422 port. It should be possible to use any RS-422 or RS-232 interface to control the glasses. The glasses cost about $50 and the parts for the interface are about $10. I have written a document on the interface and it is currently being reviewed by a few of my friends. When they decide that the document is correct (i.e. they build their interfaces using the document), I will post the MacWrite file in comp.sys.mac.hardware. Since most of you can not read the MacWrite file, I can also make MacPaint, TIFF, GIF and EPSF files available on anonymous ftp. If you think that I should also post one the files in a newsgroup (like comp.graphics), please mail me and vote for a file format. The files will be around 30-50KB depending on how much I have to extend the current document. The glasses work quite well and most people notice the 3D-effect. Controlling them from a Macintosh takes less than ten lines of code. Controlling the screen is somewhat harder... Macintosh-specific question follows: If anyone has information on the 8-bit Mac II graphics card, I'd be very interested. I need information on the card registers. Optimally, I'd like to have two 4-bit buffers and switch them at 60 Hz. Changing the clut without SetEntries (or a control call) would also be ok. _._._._._._._._._._._._._._._._._._._._._._._._._._._._._._._._._._._._._._._._ | Juri Munkki jmunkki@hut.fi jmunkki@fingate.bitnet I Want Ne | | Helsinki University of Technology Computing Centre My Own XT | ^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^
