Oh, yes, sysadmin'd several DEC-20's, some at the Columbia University computing center, some at the MIT-EECS department (working for Joel Moses) (though the homegrown LISPMs were a lot more fun) and some at the Fairchild AI Labs (a startup for Schlumberger under the Fairchild umbrella in Palo Alto, populated by the principal ex-SRI AI folks, where the Symbolics LISPMs eventually took over). And, yes, lots of happy memories, especially for the poor students when all the CRTs would send out their chorus of feeps and simultaneous %DECSYSTEM-20 NOT RUNNING messages (as sent by the PDP-11 front end). That effect was most pronounced at one of the huge Stanford terminal rooms (where, luckily my buddies (Ralph Gorin, Marc Crispin (of later IMAP fame), JQ Johnson, anyone?) were the sysadmins, and not I ;-).
