I looked at the spex today in a store.  They're pretty cute, but there
was a severe flicker (at least for me, I have a high sensitivity to it
anyway).

I want to hook them up to my PC and do some hacking.  
They plug in to the joystick port.  Does anyone know exactly what the port
does to the display circuit.  I'd assume it just does a +5/0V square wave,
but the Amiga joystick port does a lot more than the PC joysticks or 
parallel ports do.  

Has anyone run a 'scope on the joystick signals and figured out exactly 
it works?

Thanks,
