I have tried the following:
     1   2   3   4   5   6   7   8   9   10
    --- --- --- --- --- --- --- --- --- ---
S1 Off On  Off Off Off Off Off Off On  Off
S1 On  On  Off Off Off Off On  Off Off Off
S1 On  On  Off Off On On  Off Off On  Off
S1 On  Off Off Off On  On  Off Off On  Off
Maybe some others, never get anything to the screen.

I have some cards that are marked TP1:Red TP2:Blk TP4:Clr
and other cards marked TP1:Red TP2:Clr TP4:Blk
I would really like to hear from someone that has it working rather than 
risking popping something.
