On the left of the briefcase computer are numeral keys. These seem to have come from a Remington Rand Printing Calculator or something similar; that was 1957 vintage, so likely starting to become broken and obsolete by the time the prop department was looking for stuff to strip. Unfortunately these items are rare and expensive. Fortunately, very similar keys seem to have been used later on a series of Remington adding machines, which are much more numerous and much cheaper. the keys themselves look about the same, but the fonts used are different… compare the “8’s”.
I’ve not found the keys with the mathematical functions. Those looks structurally identical to the keys from the Super Riter typewriter, so they’re doubtless also a Remington product. However, for a prop reproduction cast copies with appropriate symbols printed on them would seem perfectly acceptable.
Above the numbers are six low buttons. Not quite sure what these are… might be push buttons, might be indicator lights.
