Ohhhh the turbo button. I remember that from our first 486DX2. The case had an oddly satisfying neon green segmented LCD display for CPU frequency that would drop from 50 to 25 if you disengaged the switch. Why anyone would ever willingly do so is still beyond me.

Some games had animations based on frames, not time between frames. So they where unplayable without reducing frequency

One day I switched off turbo while playing Test Drive 3.

Suddenly, I didn't need superhuman reflexes to play, and could drive on curves at speed :-D

From my very vague memory, Reader Rabbit was one such game that was unplayable at a higher CPU frequency.
