LEGO Logic Gates

`A few people have designed boolean logic devices using LEGO pneumatics and gone on to develop fundamental computer devices such as full-adders and flip-flops. [..]

I have now designed working NOT, OR, NOR, AND, and NAND gates. Using two NAND gates I have produced a NAND gate latch or Flip-FLop. The natural follow on from these is clocked logic, full-adders and ultimately a genuine “computer” device.’
