Lo from Staffordshire, UK.

What do I do with my classic miggies, play games.
Settlers, Theme Park, Cannon fodder, there are loads and loads of great games which just fly on an 030 miggy.
If you pop into a.org's IRC chat room you will often see Rockape chatting on his 030 A1200 which is hooked up to broadband, he surfs the net, chats, does e-mails all on an 030 Miggy.
As for OS3.9.. I wouldnt tbh, it slows an 030 down a lot, an A1200 with an 030 card and os3.1 is very fast but running 3.9 it does seem rather slow imho.
