SDF UNIX Shell

I know I found this a little late to be much use for the challenge, but it's worth a look for anyone who likes using old computers to do stuff. It's called the Super Dimensional Fortress, and they offer UNIX shell access to nearly anyone. All you need to do is TELNET to sdf.lonestar.org and login as "new" and follow the prompts. Your free account lasts 200 days, otherwise you can pay $1 and you get to use it for as long as you're an active member. Or you could just sign on with a different user name every time your old one expires. And it's a true UNIX shell, not just some fake shell like other places have. It runs on FreeBSD. Give it a try.
