That looks like an Apple Extended Keyboard, with an IBM sticker. In your image, it definitely looks like the "cloverleaf" symbol found on a Mac's "Command" key, along with the Option key. The key text looks like that standard Apple keyboard font of that period, and you can see where the marked over the Apple logos... both on the Command key, and the Apple logo directly under that fake IBM logo!
You can also spot the "nubs" next to the Escape key. There is another nub like that not he right side of the keyboard.
Also, if there are other angles in the movie, Look for the flattened Power key in the top right corner if the movie has another shot of the keyboard that shows that particular view. I haven't seen the movie in years, so I don't recall if that angle is ever shown or not.
