Re: More info A curious small circuit baord from a "]["?

Particularly since you talk about this going from the keyboard cable to the 
game port, I would imagine that this could possibly be the old "shift key 
modification" for the ][+ machine.  

You might have a ][+ motherboard that was installed into a //e case with this 
modification made to enable the shift key for lower case characters.  Sounds 
like a strange configuration, but not necessarilly unimaginable...  Stranger 
things have happened! :)

If memory serves correctly, the original "shift key mod" for the ][+ machines 
involved taking a wire from the shift key dedicated pin from the ][+ keyboard 
going to the game controller into the input for one of the paddle controller 
buttons...  I remember building this into my original B&H "black apple," and I 
can see it in my mind, though through a rather thick cloud...
