Just use a push switch instead of a clock pulse.

I would probably just use a microcontroller to save the hassle (like a PIC) but that requires the hardware... I could burn a PIC if you want and if i get the time to do so (low on free time lately)

that other bored posted above reminded me of that, there is another chip ment for digital clocks, it's like a pulse counter, you could use that, altho i think it puts out binary, i'm not really sure, but it might work for ya, look something like that up in mouser or something,, or maybe i'll look at get back to ya
