Hey, I was wondering whether a properly built CMOS 555 clock will
produce effects when the pin has not been removed from the gate array.
I wanted to test these out before I made any alterations to that
chip. In other words, if I just hook the output up to appropriate
pins on the gate array, so that its getting two clocks, should it make
some crazy pitch effects, even if screwy

To the guy who needed an LCD, I'm still doing repairs, but it looks
like I will likely have a extra working LCD anyway, we'll see.
