Amirc should run if you use a small tcp/ip stack, i used amitcp on the a600, amirc ran for a few thousand lines before crapping out. Lynx, hmm, well you'll need the ixemul library which is a few hundred kb(?) and ixnet. i guess there might be a port that doesnt require this.. But do try

Theres a 1 meg upgrade on the thing, right?
