A counter normally starts at zero and increments through its max
count and then returns to zero. Do you really want to count 1 through 9?
The CD40160 should work well...use the carry output to preload
a 1 into the counter. You will need a decoder to convert the BCD
into a 7 segment pattern for use with a 7 segment display. You will
need a few more passive devices and a power supply to make it go.
