Blizzard 1200/4 need help to identify mhz
When i have searched for some info i can find
optional PLCC FPU, 68881 / 68882 @ 14, 20 - 40 MHz without an oscillator the FPU can run only at 14 MHz with a suitable oscillator installed, it can run between 20 and 40 MHz On my card it says MC6882FN40A which is 40mhz. And the oscillator says 40.00000. Why do i get this strange stats? Shouldn't it been 40MHz?

I think you need a Jumper on B when you have a 40 mhz crystal.

Thanks for the reply 1time. I see that my card is a bit different in design to the one in the manual. Which one do you think is Jumber B?
Red, Blue or Yellow?

No clue... Try each one. See if you get the result you are looking for with the same tools you did before.
