Interlisp

InterLISP was the variety of LISP which ran on the Xerox 1108 and 1186 AI Workstations (which were repackagings of the Alto and Star desktop publishing workstations, respectively.)

In 1987, InterLISP was ported to the Sun Microsystems Sparc 4 archtecture by a team at the Xerox AI Systems Sunnyvale Headquarters. Later that year, XAIS, which had been a money-loser for some time for Xerox, was spun off into Envos Corporation, which almost immediately failed.
