Cube's 450MHz G4 in a 350MHz Sawtooth
Posted by: TheMacGuy on 2013-03-31 16:12:44
I was going through my part bin, and at the bottom, I found the Cube logic board and G4 card. I have no idea if they work, and remember the Cube was drowned in Coffee, but I was wondering if I wash the CPU board with a soft toothbrush under warm water, will it still work afterwards? I would just clean the back, and would try not to wet the connecter, but I would like input before I do so. Also, are the Sawtooth and Cube cards swappable?

Check the CPU card - if components look corrosed/damaged, I wouldn't even attempt to fire it up. Don't use tap water (or even a toothbrush!) to clean electronic components. Something like contact cleaning solvent/spray, or isopropyl alcohol would be much better.

And yes, the Cube CPU runs @ 100mhz bus same as in a Sawtooth motherboard, so it is interchangable (unlike if you put the same CPUs in a 133Mhz G3 like a DA where you would need to adjust the multiplier on the card itself)

I don't see any corrosion. Here are some pictures:

That looks fine to me mate - I'd try it out in your Sawtooth, free 100Mhz!

I think the "washing" of faulty components is pushed a little too frequently on here at times - if it looks clean, no obvious damage, there is no need to resort to this sort of stuff unless you have absolutely nothing to lose. Normal water should not be used near any components, unless you found it wet (and in that case, dry it out as fast as you can - I've found some awesome soaked parts that worked a treat once left to dry for a few days!) 😀
