I got the CPU upgrade for my old model 700 when the IBM PC Outlet was dumping them for $99 (instead of the original $595). It came with a nifty little chip removal tool and instructions on how to replace everything. The thing about the 486SLC chip that the 700 & 720 used was that it was so darn small. The 387SL math coprocessor took up about twice the area of the 486SLC chip. The actual hardware change took about 15 minutes and an additional 10 minutes spent reinstalling the reference and diagnostic diskettes. Installation might be different on the 755CE, but I was under the impression that they had made things much easier to access on the newer models than on the old 700/720 (eg. pop up keyboard).
