          Turbo was on by default. Pressing the button to turn it off made the computer run slower to emulate an 8086, so that software coded to calculate time based on instruction cycles rather then using a proper real time clock function wouldn’t run faster than the intended speed.

          An 8088 wouldn’t have a turbo button since it ran at the same speed as an 8086 to begin with.

          (Also, SimCity 2000 required at least a 386.)
