- zeagle 2y agoThe linked article suggests it could be both ways for button behavior. But I see what you mean for how it achieves it.
- seritools 2y agoYup, on many boards you could either jumper the direction (turbo switch closed= slow or closed = fast), or set it in the BIOS.
- deaddodo 2y agoIt could work either way. It would be better to phrase it as "outside of turbo mode it operated as a 4mhz 8086, with turbo it operated faster (usually the CPU's actual rated speed)".
- _nalply 2y agoHah that reminds me of the way of a supermarket chain to shill rebates. Turbo button not pressed, run at lower speed than rated Turbo button pressed, run at rated speed No rebate, sell at a huge margin Rebate, sell at a minimum margin
