I thought Netsurf requires 64MB and RTG in any case? And it recommends an 060? I'd try iBrowse or Voyager, instead.
I have an A1200 with a 50MHz 030 (before that, a 40MHz 030.) iBrowse is balky, especially with Javascript, but it's fairly solidly in the "usable" category. Voyager is better, but less featureful. I haven't tried ALynx as I couldn't get it to work, but I imagine that would be a lot more usable.
