    To all experts:

    I am newbie in electronics, I just want to ask if you have there simple schematic diagrams about 0-99 counter with using only 74LS192, 74LS47, and NE555?

    Any immediate response would be highly appreciated.

    Is this homework for a course?

    At what speed do you need the counter to count?

    Have you looked up the datasheets for these parts?
