          Hmmm, seems to me that if Leo wants to stop people from doing this
      in an uncomprehensive manner perhaps he should post an example of the
      "proper" way to do it.  Since I am not quite ready to do this, I can
      not see asking others not to do so.  I'm not annoyed because,


                        A)  The conversion is relatively easy, it's
                               going to become pulic.  Why stress over
                               the inevitable?

                        B)  I don't see the Sega glasses as a threat. Our
                               glasses system is better!  Why?  Bigger 
                               lenses for one (a big plus).  Another reason
                               is that our interface supports two glasses
                               outputs.  Since our glasses are a visor 
                               arrangement, so they don't interfere with
                               normal glasses (which most of us computer
                               users wear :^)).  

                                  Probably more importantly, the look neater
                               which will appeal to younger markets.

>	Are your glasses compatable with the Hatex thingees?

        The answer to this is maybe.  Not having looked at the Sega interface,
      I cannot answer this but I will say that our interface is not entirely
        compatible with software written for other interfaces.  Leo's (rather
        dated) drivers do not work with them, but I have not explored the
        reason, which could be anything from uncompatible codeing to usage
        of some other port???

          Also, pin 9 is probably not a good way to go.  Among other things,
        the analog lines on the port are probably more desireble than the
        fire button.  (The idea was to use the alternative pin for output
        so that a normal joystick could still utilize the JS port tied up
        by the glasses).

          Finally, to those developers who have not recieved a letter from
        us, please forgive our slowness.  If you have not recieved a letter
        by Monday, please let me know so I can confirm you are on the list.
        As some of you know, we've had a bit of a delay due to lack of avail-
        ablility of the proper cables.  We've had to have them made, and
        all should be ready in a week.


                                                        Have Fun,

                                                                Wade.
