I also just read this:
Joining, or cascading, counters allows you to count from 0-99 (two counter stages). The preferred method of doing this is by connecting carry out of the first stage to carry in (enable) of the second stage and driving both stages from a common clock.
So I am guessing that I should connect the first 4510's Carry Out to the second 4510's Carry In.
And like I said before, connecting A and D when ABCD= 1001 through an AND gate, then to RESET will reset the counter to 0 so it continue. I know I should do that with one of the 4510's, but I am unsure if I need to do this for both.
Now so far, I know what Carry In/out does kind of, Up/down, Reset, Clock. I am unsure of Preset Enable on the 4510, Strobe on 74157 and I am still not sure what select is actually supposed to do. I also don't know if I will be using the Cin on the first 4510 and the Cout on the second 4510 at all.
