Can you take pictures of your turbo display? The old ones were just segmented displays and you would set jumpers to configure what is displayed when the turbo is on or off. Normally they were powered with a standard four-pin Molex connector like the ones that go into an IDE HDD.

I already know why my turbo display is not showing. The 2 pin connector with the black and red cable is not connected. The 3 pin connector with a white black and blue wire is connected. I also discovered that I only need to connect the black and the blue to my 2 pin connector on the motherboard for the turbo switch. I believe the white is for an LED on the turbo display. My turbo LED is not on the turbo display. It is separate in the case with a white and yellow wire to the motherboard. Unfortunately I don't have a power cable for my turbo display on my power supply and I don't have an adapter cable for it either. I'm going to try to make a cable myself. Let me know if I get a picture on my turbo display. I will also post pictures of it shortly. Now I have to find out how many mhz my processor is running when I use the turbo switch. Does anyone know how I can measure that in dos?

The real question is what the turbo button changes. Some simply disable cache. Some may change the bus speed. Some may do both.\

To see the speed the CPU is most likely running at, download Phil's DOS benchmark pack and you can look in:
CHKCPU and SPEEDSYS.

Both of those show the Mhz of the CPU. CHKCPU says it is not necessarily accurate if the cache is disabled.
