From the Wikipedia article about Star Trek IV.
"The model of Apple Macintosh computer shown in the Plexicorp office scene is the Mac Plus. According to rumor, it was intended to be an Amiga, but Commodore required the producers to purchase a computer while Apple was willing to lend them the machine shown. Amigas were used to produce the screens of the Vulcan computer used by Spock to re-train himself in logic."
:getmad: :cry:
I wonder how many Star Trek fans bought a Mac Plus instead.
