need help designing a stop watch (mod 60 counter).
using ICs:
1 - 74LS74 (D-type flip flop)
2 - 74LS93 (4-bit binary counter)
1 - 74LS32 (OR gates)
1 - 74LS00 (NAND gates)
e.g.
0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 and so on. mod-10 counter
0 0 0 0 0 0 0 0 0 0 1 1 1 1 1 1 1 1 1 1 2 2 and so on... mod-6 counter
it must hav start/stop and reset function.
