Any ideas po pano gumawa ng game buzzer using TTL Logic gates?

It is supposed to be run by this:

4 push buttons:

3 for 3-players
1 for reset.

3 buzzers:
3 for each player.

Bale paunahan po xa ng pindot. The first one to press the button would latch his/her buzzer. The remaining two pushbuttons are deactivated na po. Then the reset button would reset them.

Hingi po sana ako ng ideas or concepts. Or even schematics if u have already tried this one. Thank you po any ideas will help a lot! Smiley

ito yung ginawa ko.
pwede mo gawin apat o higit pa.
dagdagan mo na lang ng (1) count down/up counter para sa time limit to answer and (2) one shot buzzer as suggested by kinyo para sa indication na may nag press ng button.

Yung R=reset. post your schematic diagram.
Mostly this type of circuits used Flip flops.

Nagawa ko na yung 8 input quizzer version nito.
Digital board almost done. But Relay board is still under development.
Hindi pwede yung mechanical relay, due to electrical noise will affect the digital board.
Relay board will modified to SSR or its equivalent circuits.

Ito yung 4 quizzer input version.
