Gremlin missed the real bottleneck. He assumed the delay was just waiting for
the floppy disk, but on those old machines, "fancy" high-level code actually
bogged down the CPU. While a normal program clumsily checks one byte at a time
-- wasting effort on every step -- you used a hardware shortcut to verify the
whole block in one smooth motion. You can't make the disk to read faster, so
you made sure the computer didn't choke on the data once it arrived.

I hope he can stick to this. Sincerely.
