One of my machines has a "Turbo" button that changes from "HI" to

It does make a noticeable difference in speed. Probably inserts a
bunch of NOPs in or something. Comes in handy when I'm trying to play
older games.
On older machines it did actually change the clock speed.
One of the memories I have from my first school in Norway were being
thrown out from the computer room for (unknowingly) violating the rule,
and I quote:
"The Turbo switch must be turned OFF to preserve the hardware."
The computer teacher really did believe that using the Turbo button
would cause the computers to wear down faster. And yes, there was a
(very!) noticeable slowdown when the Turbo button was off. This was a
486 running Windows 95.
