- If anyone recalls Peter Rony's BugBooks from early microcomputer days,
- they are full of simple circuitry. A word of warning: IC's are based on
- NAND gates, whereas WireWorld seems to work better with NOR gates. So you
- get to reinvent the wheel (microcircuitry) all over again.
- -
- The closest Wireworld comes to boolean constants are pulse trains, so the
- place to begin is first with clocks, then with the traditional boolean
- functions, finally create delays, and crossovers. From then on, it is just
- one huge construction project.
- -
- Some simple, but cute circuits:
- -
- 1) an electron mirror - sends a single pulse back where it came from.
- 2) single pulser - only lets the first pulse of a train get through.
- 3) pulse doubler - emits two pulses for each arrival.
- 4) train trigger - emits continuous pulses once triggered.
- -
- After that, there is the whole family of flip-flops (D, J, K, ...), binary
- counters, incrementers, adders, ... (even your own Intel 8080).
