“The Motorola MC14500B is a 1-bit processor introduced in 1976. While a 1-bit processor might seem almost useless, it was marketed as an Industrial Control Unit for applications that made simple decisions based on Boolean logic, for example, air conditioning, motor control, or traffic lights.”
“You might think that a 1-bit processor would only support two instructions, making it impractical. However, like many processors, the MC14500B uses different sizes for data and instructions. Although it used one bit for data, its instructions were 4 bits, giving it a small but usable instruction set of 16 instructions.”

very nice looking PCB, though some more details would be nice.
block diagram, specs, etc.
also, my guy, have you heard of our lord and savior resistor networks?
very useful when connecting multiple LEDs, or pulling multiple logic lines up/down.
