does the 060 use need an 100 mhz crystal to run at 50 mhz as a 040 does or does it need a 50mhz crystal to run at 50 mhz?

040 is working on clock speed divided by 2.
Example for Apollo 1240: Oscillator is 66MHz so 040 clock is 33MHz

060 is working on clock speed.
Example for Apollo 1260: Oscillator is 66MHz so 060 clock is 66MHz

I did think that to be honest but I'm sure I read someone say the 060 was the same as an 040 ahhh so I need a 50mhz crystal then after all :)

Thanks for the info :)

If your Apollo 1240 is 25MHz model you have 50MHz oscillator on the turbo board already, don't need to buy another.

I made that mistake in another thread. I'd assumed the same as you that if an '040 needs a double-speed oscillator, then the '060 would too. Apparently this isn't the case.

@mjnurney: If you actually need an 50mhz crystal, just PM me for the details. It's the rectangle-shaped one i got, not the long one.
