https://en.wikipedia.org/wiki/Turbo_button https://en.wikipedia.org/wiki/Turbo_button I know the chip was a 66mhz chip. Without the button pressed, it was useless. I also know this was about CPU timing. Having it "on" slowed down the timing. But having it on (to slow the CPU timing) and trying to overclock the CPU (to make it faster), resulted in nothing more than a few fps. After the upgrade to Pentium, it was 60fps. The turbo button is a 3-pin switch. Some wired it so that "off" was full-speed. Some wired it the other way. I believe mine were wired for "on" = fullspeed.
