To my surprise, it worked this time. I don't know if you can see it with your admin powers, but I'm on IE 4.5 running on MacOS 9.2.1!
The layout is completely f'ed up, but I can now login and (if you can read this) post.
I just got 256mb of ram through the mail today and bumped the overall memory to 288mb. Maybe that has something to do with it? I'll try Classilla next and see if the website is presented correctly.
