    Hi,
    I wonder if anybody could send me a solution to this problem. It´s for university and it comes nearly in every exam. Many thanks in advance.

    Create a bi-stable RST (with reset and preset) only with circuits 7400 and 7432 and paint the connections.
    Send a chronogram with signals R,S,T and Q. Initial status is R=S=0 Q=0, and S=1 activates with a clock cicle. Signal T is connected to a clock.

    Just get the internal logic for a flip flop and use that as a guide.
