I have 3 5150's, 3 AT's and some other early IBMs if you are interested. Where are you located? I am in Mojave, CA so if you are in southern California I might be able to help. Also, what is the setting for the film? I also have 3 monochrome monitors (model 5151), a CGA monitor (5153) and an EGA (5154). I have manuals and software if you need something like that for props as well.
