Expansion Module 1 edge card pinout

[rietveld]

Hi.  Does anyone have the pinout of the Expansion Module 1?

 

I want to see if I can make a switch that allows it to be left attached to my colecovision and just flip the switch when i want to play Atari games.  I understand that it is only one pin that grounds out and enables the module.  is this correct?
