    Please explain? I get that the chubby bird is speaking assembly, but I’m sure there’s more to it than that?

      PS2 keyboards use interrupts rather than polling in USB, meaning every time a key is pressed the CPU stops what its doing to process it.

          Super IO does still use interrupts as far as I know. The PS/2 protocol is interrupt-driven, so it’s not possible to use a PS/2 keyboard or mouse without interrupts.

        And having to pick your IRQ when installing anything into your machine, and the weird bugs that could happen if you mucked it up.

          I know you’re probably being facetious… but the PS/2 port is what’s shown in the OP image.

          that said the Playstation 2 had USB ports, you could just plug a regular keyboard into it
