        As you suspected, it is impossible to use the glasses in interlaced
mode.  Depending on which piece of software you are using, trying to utilize
interlaced mode will achieve varing results.

        I believe that if you use M3D with interlaced pictures you will get
a double height picture in each view. i.e. you will see the top half of the
picture stretched to full screen height.  I wrote a version of M3D that
checked for this and sliced out every other line, but I'm pretty sure this
did not go out (v1.06).

        As far as flicker goes, it really is desireable to dim the room
lighting if possible.  While the screen flickering is generally not to
irritating even in bright non-florecent lighting, as you pointed out, the
rest of the world will flicker annoyingly while the glasses sync to the
screen, and more significantly the edges of the monitor will create an un-
wanted frame of reference if you bring images out of the screen.

        Also, you will want to keep in mind that if you want to put your
images on video-tape for (future) stereo viewing, you will defeat your VCR's
interlaced output just as you do with the current Amiga output.


                                                        Good Luck,


                                                                Wade.

PS:  With any luck a fairly comprehensive X-Specs support library should be
released by Haitex any day now.  It is done and tested so???

     Also, given that the Impulse/Sega glasses combo run about the same as the
XSpecs glasses, why would you buy Sega?  XSpecs are clearly superior.
