Details:

In many machines the carriage is mounted on top of and outside the machine.  The Facit has a very compact mechanism mounted inside. Unusual is the use of an alternating current motor in stead of the more usual universal motor.

In 1974, Büromaschinen Lexikon still mentiones the Facit 1007 similar to the CA2-16 but with a plastic cover. However it doesn’t  mention it’s price anymore. It was catalogued as:  “Price on request”.  By this time electronic machines with memory were smaller, faster and much cheaper than the 1007.  They must have been hard to sell.

The photo left-under shows two repair notes, one mentions the removal of grease, the other the replacement of a machine part.

The photo right-under shows the replica of the user manual. It was printed from a .pdf file.

Usage:

Addition/subtraction:   

Enter a number, then push the “+” or “-” key. At the end of the process both clear the Reg - I   input register.

Multiplication:

Enter the 1st  number,  push “X”,  enter the 2nd  number, push “X=”

Square:

Enter the number to be squared, then push “X=”

Division:

Enter the 1st  number, push the “:”, then enter the 2nd  number and push the “:=” button.

Function of some keys, switches etc:

• The “R+” or “R-” key are similar to “+” and  “-”, but do not clear the input register.
• Addition/subtraction operations ate not counted in Reg-II, unless the white key Reg-II is pressed.
• “A+” and “A-”  add/subtract the contents of Reg-III in Reg-II.  So actually using Reg.II as a memory
• Both, Reg-II and Reg-III can be transferred to the input register Reg-I using respectively  “IIv”  and “IIIv”
• The small keys “16”, “13”, “9”  determine which digits will be transferred.
• The “C” key interrupts a division.  An endless division (e.g. when accidentally dividing by zero) can be stopped.
•  When the “NEG” key has been depressed register-II  subtracts instead of adding.
