LIME Lisp Machine

In February 1990, Japan Airlines (JAL) and NEC announced the joint development and operation of a system which was the first in the world to use AI to quickly generate monthly flight crew schedules for their entire flight staff of 2,200 employees. JAL and NEC started research and development on this system in 1986, and it was used in full-scale operations after use on a trial basis. The basis for this system was the LIME, a Lisp machine developed by NEC.
