Olympia RA16


At first sight this little machine isn’t very impressive.  It lacks the large amount of buttons, switches and levers spread all over  the machine as you find them on many high end machines of competitors.  However, it appears to be a very capable machine.  Inside I noticed the absence of adjustments.  The Hamann 505 and Friden SBT10 for example have many adjustments.  The Olympia ...... I didn’t see one ...

Contrary to most other machines,  the right register (reg. II)  does not count the number of operations. It can be used like reg III for addition and subtraction.  So, there are two independent registers to work with.
Furthermore back transfer is possible from each of these two register to reg I.  This also makes it  possible to transfer a number from reg III to II and v.v.  There is also an 8-digit memory. It is located at reg II and can be connected to reg II when desired.  Ones connected, a clear of reg II transports its original contents to that memory.  Back transfer and memory make this a very flexible machine, suitable for complex calculations without writing down intermediate results.



As usual using the “+” and “-” keys.  Reg. III (left reg.) as well as II (right reg.) can be used.    For that purpose the arrow keys in the left part of the keyboard allow the carriage to be moved to the centre for calculation in reg. III  or to the left for calculation in reg. II.


Enter 1st number,  push the ‘X’-button,  enter the 2nd number, then push one of the following keys:

the “=”-key to add the result to reg.III
the red “=”- key to subtract  the result from reg.III
the “=III” key to store the result in reg. III  (clears reg. III in advance)
Remark:  The carriage is automatically positioned in the proper positions.


Enter the  1st number,  then push the “:”-key,  next enter the 2nd number and then the  “<---“-key . The result is put in reg. II.

Remark:  The carriage is automatically positioned in the proper positions.
