Thanks for the responses. So, my computer did have the classic networking, which I couldn't get to work. So I managed to find a copy of Open Transport and installed it onto the computer. Then I simply set it to configure automatically and it worked!
You weren't joking about it being slow though, its really slow. I only have 8 mb of ram though. I did try out WannaBe, which is a text only browser, and that's fairly quick, but very limited and formats things strangely most of the time. iCab is pretty good, but just very, very slow. I actually managed to log onto my gmail account and send an email, using the basic HTML version of gmail. I also tried out an RSS program that seems to work, although again formats things strangely. I'm looking into what else I can do.
