Hamming is an x86-processor based VIA EPIA based system donated by User:Aden. It is old and was once doorbot. It ideally could be replaced with a modern Raspberry Pi 2 or Beaglebone Black.
It's also connected to some speakers so it can do the doorbot-sounds (historically GLaDOS voices) as well.
It has 2 x hard drives in RAID1, which is nice. It also runs X and can do TV out (maybe) so could connect to one of the CRT TV's for extra grimy retro ness.Useful note for crashes / restarts etc - run
export AUDIODEV=hw:0,0before rebooting listeners.sh or PulseAudio won't work.
