I have installed xp on many older laptops people buy at yardsales ranging from p133's to p300's, with 128mb ram. It is no problem except waiting for 32x cdroms to read the cd lol. I would say your best bet is to turn off all the visual eye candy, and learn how to trim your services way way down. The laptop I use with most is an old Micron p300 with 128mb ram and xp pro sp2, because the batterly life on it still beats out my new mobile cpus. I code on it and use internet. Sure you won't get that instant response like a new computer, but I would hardly say it is unusable. IMO the best av for this type thing WAS f-prot, but the old version no longer has updates, and the new version I don't know about. Keep your running processes to a minimum and shave the eye candy, and you might be able to get better av performance. I have given dozens of computers to people for next to nothing. I have bought them from the schools for $5 when they get rid of them, OS and all. I even bought 10 nice 1.2g machines with xp pro oem keys for $10 each last year. Another place is community colleges and large businesses. Often they offer older machines to employees who don't want stuff that old, and they gladly give them away or charge very small price instead of paying to have them taken somewhere. You can check resources like these out and then strip down machines for upgrades. Sul.
