    OK.

    Thanks again.

    Does anybody know a cheap circuit that I can add on to one of the outputs to compare that clock to an existing one and light an LED when they are the same?

    Please don't let this fade to the land of unread threads.

    I need this circuit before Friday so I can test it and finish my NES overclocking guide.
