But Does It Play Doom?

Someone has shoved NetBSD into a toaster:

A full NetBSD installation is on the 512MB compact flash attached to the TS-7200. This includes self-hosted compilers, FTP/telnet server, ssh client/server, crypto libraries, kernel/userlevel debuggers, and standard UNIX utilities. Apache with PHP is also installed on the TS-7200 and presents some CGI programs to control the LEDs, play music, etc... Since the 4x40 LCD is attached as a generic console, manipulating text files is also reasonably possible using installed text editors, though admittedly using vi on a 4 row text display is not particularly productive.

Humorously, that keyboard pictured is the one I use at home.
