Old Calculators

These are two old (older than the Wang, see earlier post) calculators, pre-pre-cursors to computers. Neither of them are fully transistorized, they incorporate mechanical parts to assist in performing calculations.
The top one was made by Burroughs, and the bottom one made by Friden.
