Hi everybody, I have a quick question. I recently bought a Powerbook 1400c/166 on eBay, and while I was looking through System Profiler, saw it said it was a 67Mhz PowerPC G3. Now, I know that's not right. So I popped it open, and took a look at the CPU. The processor says IBM PPC750L-GB500B3 on it, but has no other markings. Now, I'm going to make a guess and assume this is a G3 upgrade card? I can't find any specific info on this anywhere online, so I turn to you. The only things I can find is desktop CPU cards with the same markings, but they're 500Mhz G3's. Did they even make 500Mhz G3's for the Powerbook? Anyone have any good guesses? Update: Ok. So I turned on the extension for a Sonnet Crescendo (missed that the first time through!) and now it says it has a 233Mhz G3 in it. From what I can tell, Sonnet never made a G3 upgrade that slow for the 1400, and this is most likely a 466Mhz upgrade which shows up as a 233Mhz in the System Profiler. Apparently Sonnet uses some sort of "bus doubler" to get the 466Mhz. I'm not sure. Anyone know any more than what I've dug up?
