The previous two articles about ALU design did explain how to turn
(nearly) anything but the kitchen sink into an ALU.

This article explains few strange/peculiar things that went unmentioned.

• Two-Pole-Double-Throw Relay Adder
• Four-Pole-Double-Throw Relay Adder
• Decoder
• Relay ALU
• MC14500 and arithmetic
• A MC14500 modification
• CM-1
• 8 Bit ALU with Bit manipulation
