When I saw the 4 bit computer I just had te build one, and so I did. I had some problems, I mounted the LED's the wrong way arround
and I had some minor problems witch were quickly resolved.
I still have 1 problem, and i wonder if I'm the only one? The machine works perfectly until I add a sum with a total of 24 from uneven numbers, the machine says it is 16. For example 11+13 and 15+9 become 16
. But 12+12 and 14+10 become 24
. I just can't get my head arround this problem. Did I make an mistake (hey I'm only human)? or do other people who buildt this machine have the same problem. I hope somone can help.
And for the record, Great Project!
