I have recently aquired a 486 sl/33 thinkpad for $20. I am quite pleased as all I need it for is Text editing for Languages like C etc. Never having owned a laptop I am unsure of my options for upgrading the tuiny processor. Can it be overclocked? can I throw a dx2-66 chip in it? How to I upgrade the 340mb Hard Drive.

WHAT ARE MY OPTIONS? are there any good websites on the matter apart from IBM?
