When beginning, don't think that big - making your own CPU is cool, but 
is very involved.

Think - "I want to make a counter" and wire up the chips to count.


A device like this can be very practicable - I use a BCD counter to 
count windings on electromagnets that I make.  3 chips and a bunch of 
breadboard wire.  No computer or programmer required.  Tho with a basic 
stamp you could hook up something similar and do the counting in program 
code.
