Turbo switch, display on AT case

[yoshald]

Hello. I have a lot of experience when it comes to ATX machines. I recently picked up a used AT machine (FIC PA 2007) very cheap, upgraded the BIOS, and went from a Pentium 150 to K6-2 450. The front of the case has the goofy LED display for showing the clock speed, but it's wrong of course. My understanding is that some old, poorly written software required a system to be slowed down so the code would run. When I'm in windows, and i hit the turbo button, it goes between 08 and 133. Benchmarks clock the CPU at 450 either way. When would the turbo button really work? Does it only work with some CPUs? Is there a way to disable the case LED and turbo button,or is it better to leave it alone?

Also, from the power supply's power switch there is a grean wire dangling. Is this a ground? I'm guessing it should be screwed to the case?

The mainboard is a FIC PA 2007.

There should be a heap of jumpers on the back of the display panel. Play around with them for a while and you should be able to change the reading on the display. If it doesn't matter which way you're turbo button works and the CPU benches the same all the time, set both the on and off settings to the same thing.

"Turbo" buttons were only connected to 486 class motherboards, where they would slow down the CPU when not pushed in. They do absolutely nothing to a machine like yours. The MHz display on the front of the case can definitely be changed but the jumpers are pretty complex and hard to reach without dismantling the entire case. Since it's a purely cosmetic issue, I wouldn't think it's worth the effort.
