Visit Darth in the Northwestern Sector (as we call it out here) and you'll also be able to make a fone call over the miniature step-by-step exchange the Telco Lab guys built a couple terms back.
[size=8pt]They didn't want it after they returned from the phreak/telco exhibition they were showing it off at nearing the end of last term and were just going to dump it, so we have it in 141 as part of our exhibit/educational focus. It works, too, and is tied in to the University's fone system on its own extension--if you call 2-1070 and enter just about any other four-digit extension in the 3000s group after the second dial tone, you'll be on the step system and right in the lap of electromechanical telephonic luxury.
WMC, I believe your Father felt quite nostalgic seeing and using a working step system in today's world when you brought him to the campus a couple years back, correct? ;o)
