[rec.games.video] Stereo Graphics for $60

jmunkki@kampi.hut.fi (Juri Munkki) (10/25/89)

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.
