Bought an original XBOX a couple of days ago because I wanted something to tinker with. Installed a modchip and created my own FTP server boot disc loosely based off of a pre-existing FileZilla port that provides all files on the HDD, EEPROM dumps and system info. Probably not even going to use it to play games, it's all about making it do things it wasn't intended to.
Also worked on a project that downloads entire sites from the Wayback Machine at a certain point (or as close to a certain point as possible).
