Turbo button
The turbo button was used on computers using the Intel 80286, Intel 80386 and Intel 80486 processors, from the mid 1980s to mid 1990s. The name is inspired by turbocharger, a device which increases an engine’s power and efficiency. Engaging turbo mode slows the system down to a state compatible with original 80868088 chips.
About Turbo button in brief
The turbo button was used on computers using the Intel 80286, Intel 80386 and Intel 80486 processors, from the mid 1980s to mid 1990s. The name is inspired by turbocharger, a device which increases an engine’s power and efficiency. Engaging turbo mode slows the system down to a state compatible with original 80868088 chips. On most systems, turbo mode was with the button pushed in, but since the button could often be wired either way, on some systems it was the opposite.
As software began to rely on other timing methods, turbo became mostly irrelevant to new programs. Modern PCs that support ACPI power management may provide software controls to switch ACPI performance states.
