Yo... That would be me..  (for one?) 
The following contains the instructions to attach the Sega LCD glasses
to your Amiga (Xspecs software compatible)
Also included is how to attach the Sega light gun to your Amiga.
(Actionware compatible, P.O.W., Capone, etc)

How to connect the Sega 3D glasses to Joystick port 2 on your Amiga:

Sega LCD module, board with fingers pointing down, front side. Pins
are arranged in the indicated zig-zag pattern. Connectors (female) are
VERY hard to locate.  I "bummed" one off of a tech at Sega of America 
over the phone. (lucked out)

  |_|_______________________________|_|_|___________|____ Gnd

  
Pins 5,13,14,15,16,17,18,22,23,25,26,34 are No Connects (float).

1. Joystick port 2 pin 7 = +5 (connect to module as indicated above,
   pins 1, 6-12, 28-33 & 35)

2. Joystick port 2 pin 8 = GND (connect to module as indicated above,
   pins 2, 3, 19-21 & 27)

3. clk (above) can go to pin 24 of the serial port on a 1000 OR 
   If you have a 500/2000, or if you don't want to run
   a line to your serial port, you can just stick a 3.58 Mhz packaged 
   oscillator on your adapter and have that drive pin 4. (the 2000
   doesn't have a clock output on pin 24 like the 1000 has.)
   This is to provide an AC voltage to drive the liquid crystal.
   A package oscillator simply hooks to +5 and Gnd and has an output
   to drive pin 4. (you probably new that, just being thorough)

4. Data goes to pin 6 of joystick port 2.

  While I'm at it, this is how to connect the Sega gun to the Amiga.
  Compatible with the Actionware games like Capone and P.O.W.  Works great!

To Amiga Joystick port 2:              To Gun:
           9 pin female               9 pin male
