Re: Kudos for the effort....
you have to REALLY want to do it "that way" to put in that kind of effort.
It reminds me of a binary "computer" my 3rd grade teacher's son built in the 1960's (ca 1968), using discrete components. It could add 2 binary numbers, had light bulbs to indicate the binary result, and switches to enter the numbers. I was confused by difficulty of the process of entering the numbers, like "I have to do MORE math just to enter the values I'm adding, than the actual calculation". Oh, and it could SUBTRACT, too.
Now that I think of it, he must've had a lot of work to do, building all of those gates and half-adders out of discrete components...
(but there might've been RTL gates available back then, not like that would really be that much easier)
