As far as I know, the Turbo button changes the speed of the machine. Some
machines have an LED display to indicate the speed it is operating at.
Hitting the Turbo button will toggle between, say, 33 MHz and 8 MHz. You
may also be able to control the speed by hitting CTRL-ALT-<keypad +> or 
<keypad ->, thus giving you a range of speeds to set your CPU to. I'd
suggest using some utility to measure the speed of your CPU as you play
with the speeds.
