How could I make a shot clock count down without the control board? Answered
I came across an old basketball shot clock (Nevco SCD-2, from 1987) , and upon seeing it I instantly thought of new years, It would be an epic countdown. Not to mention the immensely loud buzzer that it contains. Problem is I can't seem to get any info about how the circuitry works (the clock thing is pre-interenet). The only input (besides power) is a small plug similar to coaxial that I assume sends some kind of pulse that is decoded on board. anybody got any ideas?
