"Turbo" button

[Stein Inge Asmul]

Pardon my ignorance but what the heck does this "Turbo-button" next to the reset-button on the front of my cabinet do?

the turbo button wasa a quick way to overclock for older games that 2-12mhz would see ....
(changed the FSB)....
but anyways you dont even need it nowadayz just disconnect it from the motherboard or just ignore it...

underclock is probably a better word. At the 486 level turning the turbo off would usually just disable the internal cache on the chip, making it perform more like a slow 386. If it hooked to the board, leave it, if not, leave it. Sometimes unhooking it will drop the system into non-turbo mode. You can fix that by putting a jumper on the right pins on the board, but it is probably best to leave well enough alone.

800xl is spot on, unless you have a newer system built in an old box. in any event leave it on turbo.
