In 2002 I made my second caterpillar out of steam bent Oak. I wire wrapped over 50 IC chips including NOR and NAND gates, counters and de-bouncers to control this caterpillar. I didn’t make notes about how it is wired, and all I remember is that if I had one toggle up when another is down, it will short out. But I can’t remember which switch is which and so have been afraid to turn it back on.
