About 1980, in the main terminal room in Wean Hall at CMU, late night but the place is packed because so many have assignments due the next day. The DEC-20 is under heavy load, all the DECscope VT52's are occupied, as well as the less desirable DECwriter III terminals with fan-fold paper. Many of the DECscopes are running TECO EMACS sessions, I see some people writing papers in Scribe (Brian Reid's word processing language.) Suddenly everything stops in the room and everyone holds their breath for a couple very long seconds. "%DECSYSTEM-20 NOT RUNNING" prints on every terminal in unison. Everybody cries out in anguish. Good times.
