(...) Yes, I can see how the 2-cylinder design is more cost-effective, particularly since a Backhoe has 10 cylinders and only 7 switches. That allows more cylinders to be used for AND and OR gates, saving the switches for XOR gates. I've done some (...) (19 years ago, 28-Aug-05, to lugnet.technic)

Mark, I have studied and understand your 3+3 AND gate. A few years ago I made a simpler version of the same thing. My design replaces your six switches with one switch and mechanical linkages. Here is a picture of this AND gate: (URL) In my 1 AND (...) (19 years ago, 25-Aug-05, to lugnet.technic)
