I have a friend who wants to build a arbitration circuit as part of a high
school project.  Basically all it does is determine who presses a button 
first just like in Jeopardy.  Does a commodity IC exist that performs this
function?

I assume that a debouncing circuit will be needed to give a clean logic
signal and then some sort of circuit to determine who pressed their button
first and some sort of LED to indentify the person responding first and
a buzzer.  If there is a tie then all corresponding LED are energized.

Any comments or circuit suggestions are welcomed.  Please post to this
notes group are to me directly.

Thanks in Advance!!!
