I second craigslist/Kijiji. Offer it for free if you want it gone quickly, or ask for $10 if you want to make sure it doesn't get picked up to collect dust somewhere. Kijiji has a lot more traffic, but craigslist seems to have better control over spammers and such.
I have an 8'x8' corner of the basement filled with old equipment, and I'm slowly going through it as even older equipment breaks. I even had a 386 computer running up until a few years ago when the hard drive finally died, and the motherboard wouldn't recognize any newer ones. The oldest relic still in service right now is a 90 MHz Pentium from around 1994 that is a print and file server. I'd take all your stuff, but as it is my pile-o-crap will already last me for the next ten years.
