Try MacLynx instead which's text-only, but works fine for browsing news pages and so on. Mind you, if you have 6 or 8MB of RAM, it may be possible to run MacWeb off a RAM Disk . This could make these old browsers run at a tolerable speed. MacWeb 1.1 is faster than 2.0, but 2.0 supports frames. All I can say is it's a pity you can't use the Wannabe or iCab browsers.
Email is a better bet.
1.5 addss a few more features and is more customisable. Both are fast and certainly run more than adequately on the 100. If you want to run the net, you need a faster Mac. I don't think. AOL won't work as I think you need v.3.0 or 4.0 and these don't run on a 68000.
