Monroe "MonroMatic", Model CSA-10
Technology: Stepped drum, fully automatic
Digits: 10 keyboard, 10 counter, 20 accumulator
Dimensions: 9"W x 11"D x 8"H, carriage width 13"
Weight: 25 pounds (11.3kg)
Manufactured: Orange, New Jersey, 1940s-50s
The MonroMatic CSA-10 from the 1940s is a very fast fully-automatic desk calculator in a very compact package.
To perform a division, the operator first selects the number of digits required in the result by pressing a button on the carriage tabulator, then enters the dividend on the keyboard. Pressing the "Div Tab" key positions the carriage, enters the dividend, and clears the counter register. The operator then enters the divisor and presses "Div", and the calculation proceeds automatically to completion.
To perform a multiplication, the operator enters the first factor and presses "Enter X". This positions the carriage to the left and transfers the number to the small multiplier register just below the main result register. On entering the second factor and pressing "Mult", the machine clears the result and counter registers, automatically performs the necessary adds and shifts, and returns the carriage to the left on completion. An "Acc" control allows the results of successive multiplications to be accumulated.
