Hi Folks,
I need a push button that will drive a single pulse of XTAL-1 each time
I
press it and in turn the chip
question: what chip? will respond with 8 bits

question: what 8 bits? what makes the 8 bits?
which I
would like to read manually by LEDs. Would I need something like a LS245
data latch to catch the data for the LED's to be stable??
A battery would provide the power for the chip & XTAL.Please keep it as
simple as possible as I'm not schooled in electronics.

thanks in advance.
