# coloring computers
non-electronic computers that work when you color them according to a simple set of rules.
an exploration of computation without electricity and semiconductors, an attempt to reinvent digital systems away from efficiency and productivity, and hopeful prototypes to expose the inner workings of computers.

the booklet contains three series of computers: computers that compare, computers that count, and computers that play. they are all {nor}-based logic circuits designed by using truth tables, karnaugh maps, and maxterm expansions.
