[comp.graphics] 3d-glasses interface schema wanted

wdao@girtab.usc.edu (Walter Dao) (06/26/91)

Some time ago, somebody posted the schematics for interfacing a SEGA 3-d 
glasses to a computer (the circuit was producing the xxHz pulse needed
by the glasses to turn a one of the lenses dark). 
can somebody send it to me ? (or tell me where to FTP it ?) thanks
