I remember sitting in the basement of the DCL building at UIUC one day working through an MP for my computer architecture class. We had been working up from logic gates up through subcomponents to a basic computer architecture - from multiplexers, gates, and decoders up to the ALU, program counter, clock, etc. The problem I was working on had something to do with connecting them all together such that the clock would tick, a new instruction would be loaded into memory, the program counter would be incremented, etc. The instruction had to come from the inputs from a combination of muliplexers, decoders, and so forth. These would be pins with high/low voltage, that would feed into these subcomponents to represent an instruction.
The day ALU pins expanded my brain
