I think I saw a couple of old Frieden calculators, mostly mechanical but could add, subtract, multiply and divide. They would run you $2,000 to $3,000 each in the early 1960s. More than many cars. They didn't print out the answer, but displayed it in a movable carriage and you would have to write down the answer. How things have improved.
