My first computer was an IBM 486DX@33Mhz. My father had an Apple Macintosh Quatra (Ferrari) and I had this IBM (hooptie). I remember vividly trying to get DOOM to run on it. It would but at 6fps. With the turbo switch on, 66Mhz, I got 12fps on low settings. My father and I tried everything we could to overclock that IBM into 133Mhz but the CPU was holding it back. Later that year, he bought Marathon by Bungie (precursor to Halo) for me on his Mac. I think he felt bad that I was so disappointed. I loved it. He saw this and for Christmas that year, I had a new motherboard with a new Pentium chip capable of ripping Martian marine mutant faces.

[1] I mean, you could by default power your pc with turbo in “slow mode”, and activate it for hyperspeed, but you’re still using a 66Mhz CPU that is being normally slowed down

  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.
