I *heard* that TP's use surface mount chips. I was considering an upgrade but that kinda put me off. I guess that AMD are going to charge more for the surface mount 5x86 too. Still - if you know someone who's got the tools for doing surface mount work then that's a neat idea. > OR talk to the 2 or 3 laptop upgrade companies .....I believe that two of > them even lurk around here. pepsales?? They charge about $300-400 last time I checked. Seems expensive for fitting a chip that costs $45, but they got their reasons. > The official prices for the 50 and 75Mhz boards are amusing > Note: your cost could very low if you can find an old board.

But I don't see why the 'extra' board is needed except for in case 'something goes wrong'... > BTW don't expect a big improvement .
