In many machines the carriage is mounted on top of and outside the machine. The Facit has a very compact mechanism mounted inside. Very unusual is the use of an alternating current motor in stead of the more usual universal motor.
I bought the machine from the original user. He had an administrative role in a large soap factory.
Introduced in 1956 this machine is perhaps the longest lasting electromechanical machine of the 50th and 60th. It more or less survived the beginning of the electronic era. However, while still available in 1973 and 1974, its price wasn’t mentioned anymore. It was catalogued as: “Price on request”. By this time electronic machines with memory were about half the original price of the CA1-13. They must have been hard to sell.
For all operations except division the MULT/DIV selector is in MULT position.
There is also a centre position in which the smaller chrome selector controls the movement of the input register. Set to the right the input register is stepped to the right after each operation. Set to the left the input register does not move.
Enter a number, then push the “ADD” or “-” button.
The “-” button does not clear the input register unless it is pressed together with the “SUB/STOP” button.
The “+” key is used for half-automatic multiplication.
Enter the 1st number, push “X”, enter the 2nd number, push “=”
Enter the number to be squared, then push “=”
Put the mode selector position “Div”, enter the 1st number, push the “<--.”, then “ADD”, enter the 2nd number, “<--.”, then push the “:” button.
