Fred,
This is a different blog post. In this one he talks about how they found a
way to see if a disk was inserted in the floppy drive without spinning up

Just wondering if anyone (Chuck, Fred?) knows
what is the exact
technique referred to in this other post by Raymond?
As I understnd it, they just used a stopwatch and watched a couple of
their people change disks.
Since it was always 2 seconds or more, they used that as the number.
