Hi all,

It seems like the oscillators for the 386s I've seen run at some odd speed and not exactly double the rated speed. Example, 66 MHz is 66.437MHz for a 33MHz CPU clock.

What is the tolerance for picking new oscillators? Luckily my motherboard has a socketed oscillator but I am not sure which ones to pick.

Thanks!
