This is probably the right answer. Park stuff is indestructible and well designed. Mine is in its teens and as good as new.

What's going on with this screen? Is it a projector? What is the fuzzy thing surrounding it?

Happy SDF user for 9 years now. At first it was a safe place to learn and explore the command line.

I use SDF for DynamicDNS, NextCloud, mail, Anonradio, and sometimes a convenient place to proxy through.

There are enough tools and toys available for years of learning and experimentation. Enjoy!
