"ARPA Network Terminal System". According to RFC-597, Illinois had both an 11/20 and an 11/50 (11/45 variant) running ANTS; other sites also ran it on an 11/40. That could have been a local thing. At MIT, the first MIT-built LISP Machines, also housed in H960 racks, had custom logo panels reading "LISP Machine", with an illustration of a LISP two-part cell, with pointers (to other, un-shown, cells). I still have one... (the panel, not the CADR). Noel PS: In a previous message, I wrote "KA-11"; I meant, of course, 'KA-10'. Got -11's on the brain.. ;-)
