It still shows up in the interactive text adventure tEp house tour[1] (ask irving about Tep-O-Phone, or find it in the basement hallway) but, bad news: > Built from relays that fell out of a Bell telephone truck by Fred Fenning while he was failing his telephony class, Tep-o-phone was a state-of-the-art telephone switching system that let the outside world dial individual rooms, switching tEp's six external lines. It also let people call the laundry room (Mr. Washer and Ms. Dryers) to see if there were free machines. Sadly, Tep-o-phone has since fallen into disrepair with the now-widespread use of cell phones, but every once in a while it tries to connect a call for old time's sake. 1: https://tep.mit.edu/tour https://tep.mit.edu/tour They did rig the laundry status up to the Internet, though, and you can confirm it from the same Zork-like interface in the laundry room.
