Answer: Processor Slows
For hundreds of thousands of young computer users, the Turbo button was like a mystical power booster that could solve most computer complaints. Apart from the fact that the turbo key contrary to the intuition was never meant to accelerate something, but instead to slow down a computer.
In the early days of computer operation, programmers relied heavily on processor speed for timing. For this reason, thousands of applications, eg. For example, early PC games rely on the speed of the processor to control the timing of events within the application. For example, if you play a game that you want to play on a 33 MHz system on a 66 MHz system, the game will play twice as fast and will not play. The turbo button served as a hardwired compatibility tool, and turning the turbo down slowed the processor and ensured that older software ran properly.
While the use of the button and associated light was not consistent with early computer manufacturers (Some companies have designed it so that pressing the button turns on the light and actually lets the computer run at full speed while others have set it up that clicking the button off and "off" turns the turbo on.) The button only existed for Allow the end user to recall the processing power of his computer as needed. If it were not necessary to slow down the processor for specific purposes, no company on earth would have added a button that would allow the machine to run at the specified specifications.
On modern computers, this operation is performed by the operating system. System or emulation software and the turbo button have left the path of the 5.25-inch diskette drive.
