[comp.sys.mac.games] Stereoscopic Glasses

- Availability:  The Sega 3D glasses themselves are a bit hard to come by, but
     stores do have them for sale, and Sega still sells them--also, they're
     simple (two LED panels, some wire, a jack) and could be duplicated.
- Interface:  There is NO MOD to the glasses, only a "black" box costing
     at most $5.00 to build-> the most expensive part is the stereo connector,
     or maybe the IC, each at roughly $0.30, the only problem is building them
     en-mass.
- Connection: They connect through TWO PINS of the modem/printer port on the
     original design, our modified one, only ONE PIN, the DTR pin. No driver
     is required-it simply involves changing the status of the DTR. You
     could feasibly connect it to anything else, but why, if it's so easy.
     The design allows for connecting something else (ie the Mattel Powerglove)
     to the same interface, so in conjuction with the 3D glasses you have
     3D input... (which, again, hasn't gotten anywhere except for some
     academic dabbling because of the software.)
