Have never seen the movie, but could the luggage-style computer referred to be a Kaypro? http://koti.mbnet.fi/~oju/retro/Kaypro_eng.html and http://koti.mbnet.fi/~oju/retro/weng.html
I also see a Newton MessagePad on the desk in one pic - I've got that covered! Got a working MP100 at home.

Capt - definitely not a kaypro, check out one of the screengrabs
screen is very much different and no disc drives on the front.
