If you don’t want to get any work done today, you should check out telehack.com, a retro command-line museum. As its creator describes it:

Telehack is a simulation of a stylized arpanet/usenet, circa 1985-1990.
It is a full multi-user simulation, including 25,000 hosts and BBS’s
the early net, thousands of files from the era, a collection of
adventure and IF games, a working BASIC interpreter with a library of
programs to run, simulated historial users, and more.

It has lots of files, many of which were mirrored from Jason Scott’s textfiles.com repository, along with a host (pun) of Interactive Fiction and BASIC games. It also has a 6502 monitor (which you access by typing “call -151″, naturally!), a USENET archive, the Blinkenlights ASCII Star Wars animation, and whole lot more stuff out on the simulated remote hosts.

I do not know who the creator is*, but he or she did an incredible job with this project. Nice work, AC (anonymous creator)!

Happy Friday!
