Knex Computer
I have decided that it was possible to make a computer that does math out of only knex a while ago. However, when I discovered the lego computer, I wanted to make a knex equivilent.
This is the result of two years of work, and is currently in version 1.3.3.
This computer does not use logic gates, but instead runs off of a simple for loop.
My computer is able to take two digits, 0-9, and add them together, or subtract one from the other.
I guess that makes it a 3.16227766 bit processor.
