What document did you try to open?
I've never used OmniWeb or Nexis, but my experience with Mosaic and early
Netscape versions makes me think you'd have a hard time getting modern
pages to load without crashing.
I should think that Lynx or the original Line Mode browser would be OK.
  I recently got a NeXTstation Turbo running NeXTSTEP
3.3 (with patch 2
 applied). It's a fresh install, and I have a complete set of floppies and
 disks, including the development CD. The system seems to be working great!
 I've burned a CD with OmniWeb 2.7 beta 3 and untar'ed it on the system.
 Unfortunately, when I try to open an HTML document, it briefly comes up
 with the browser window, then crashes. You can find OmniWeb here:

 I'm not all too familiar with NeXTSTEP, so I'm not sure how I'd go about
 debugging this. But I figured I'd check here first to see if anyone has a
 recommended browser for NeXTSTEP 3.3. I would prefer to keep it at 3.3 and
 not move onto OPENSTEP if possible, just to keep things original.
 I also have Nexus, but I can't even seem to get it to open its browser at
 all. Document -> Open does nothing at all. Any ideas?
 Thanks,
 Kyle
