PowerBook 1400 Info
I don't have any speedup info on the PowerBook 1400's at this time, but I've got some info that might give rise to a modification for the 117MHz and 133MHz 1400's. Here is what I have on the 1400cs/117 and a 1400c/133. If anyone has one of the new 1400c/166's and wants to look for differences, that would be great.
Just so you have it, to get to the goods, shutdown, pull the battery and floppy or CD. Remove the three screws from the back. Flip it over, open the cover, and slide the grating behind the keyboard to the left and it will pop out. Now the keyboard will pop out (it rocks towards you from the back). I think there was a heatsink next, and then you get to the daughtercard. The card is held with four 3/16" standoff posts. Remove them, and the card will pop out. So this is the info I have; I suspect the 1400c/166 will not have the same resistors.
