In 1999 when the entire town was on dialup, I set up this relatively small PC with FreeBSD 3.3 and eggdrop, and hid it in the school library. That way I had an IRC bot that worked while I was offline. After a while I also set it up to automatically grab files from FTP servers for me, but getting these out from the “server” offline was tricky due to 1.44MB floppies being the only removable storage I had available.

Back then internet carried dialup charges per minute for me, so this was a huge time and money saver.
