I have already offered these to another user, so I can't answer on availability until after hearing from them, but I have 2 parts from an old laptop for any one in the U.S. only that are free - I pay the shipping as well:
TO-LINK TL-WN360G 54mbps mini pci wireless adapter B/G. I had this working in an old version of Ubuntu a few years ago, but I don't remember if it was "out of the box" or if it required a driver.
512MB PC-133 sdram for laptop
These are free - I even pay the shipping. I am a private person, so if you get these you don't have to worry about your info being shared.
All I ask is that someday in the future, if you can, play it forward to someone else with anything you may have to give away. Please thank user lkraemer - he sent me an external modem free of charge a couple of years ago when I really needed it but being on disability not able to afford it. What a wonderful user!
