What is the Turbo button on old computers for?

'Once upon a time', personal computers often have a Turbo button located next to the Power button and Reset reset button.In addition, there is usually a small LED on the case that indicates the clock frequency of the CPU measured in MHz or shows hi / lo indicating which CPU mode is running.
If you're in a hurry to think of the words that today's chip makers often use to indicate the speed when overclocking CPUs like Turbo or Boost, don't be mistaken.Because actually, this Turbo button has the opposite meaning.
In fact they appeared after Intel released the first 8086 processor, running at 4.77 MHz.At that time, many software (especially games) were developed separately for each individual machine, running on different clock frequencies.
When faster processors appear, the software runs so fast that the Turbo button is used to slow down the machine for software compatibility, so that it can run normally.
