This is one of Lazlo's machines.
Year of feature (shown above)
There is also a Symbolics 3600 (or 3670) LISP machine visible in the scene where Lazlo and Jordan are attempting to break into the Air Force system from the steam tunnels below the dorm. Lazlo types in password guesses on the Symbolics console. Later, he appears to select the new firing coordinates for Crossbow from a color display on the Symbolics machine (I'll have to go back to double-check).
Thanks, Bear. I've added this to the to-do list.
