*****************************************************

ENTER A NUMBER:
---------------
The actual number of digits entered shows on the slot above the
keyboard. If wrong digits are entered, pull the left slider [C]
to clear the keyboard.

ADDITION:
---------
Set the left lever so, that its window shows  [+/-].  Everytime
a number is entered and the [+] key is pressed, the motor starts
and the number is printed and added to memory.

REPEAT:
-------
To enter the same number more than once, pull the lever beside
[C] ( its window shows [R] ). The motor cycle starts, but the
keyboard will not be cleared.

SUBTRACTION:
------------
Enter the (negative) number into keyboard. Press the [-] key.
The motor starts and the number is printed and subtracted from
the memory.

SUBTOTAL:
---------
Set the right lever on bottom to [S]. The cumulated sum will be
printed when pressed [+].  The memory will hold the actual sum
after the motor cycle.

TOTAL:
------
Set the right lever on bottom to [T]. The cumulated sum will be
printed when pressed [+].  The memory will be cleared after the
motor cycle.

ID-NUMBERS:
-----------
An ID-Number can be entered and printed: Push the lever beside
[C] ( its window shows [N] = NonAdd ).  This input is not
registered in the arithmetic unit. 

MULTIPLICATION:
---------------
Set the left lever so, that its window shows [x].  Enter the
1st factor, press [+]. Enter the 2nd factor, press [+].  The
machine calculates the product, prints it and holds it in memory,
when the right-bottom lever is set to [S] - or, when [T], the
memory will be cleared after printing. If a multiplication loops,
PUSH THE ROUND KEY ON THE UPPER RIGHT TO STOP THE MACHINE.

DIVISION:
---------
Set the left-middle lever that its window shows [:].  Enter the
divident, press [+]. Enter the divisor, press [+].  The machine
calculates, print quotient & reminder and clears the memory.
If a division loops, PUSH THE ROUND KEY ON THE UPPER RIGHT UNTIL
THE MACHINE STOPS.

CHANGING THE PAPER ROLL:
************************
o  Open the top lid
o  Press the axle on both ends and lift the paper roll.
o  If necessary push the upper-right lever behind the rear paper
   slot to release and pull out the paper.
o  Put the axle into the new paper roll so that the paper end
   comes from bottom.
o  Push the upper-right lever to release the paper feeder and push
   the paper end into the rear slot until it can be seen in front.
o  Place the paper roll into holder by slightly pressing the axle
   on both ends.
o  Tighten the paper roll.
o  Turn the paper feeder more times until the paper is easy to grip.
o  Close the top lid and feed the paper through the window.

R E M A R K S   T O   R E S T O R A T I O N :  
====================================================================
This VICTOR AUTOMATIC was found "New-In-The-(Oben)Box" ( together w.
power cable, instruction booklet & plastic cover )  in an old office
supply store in  Southern Oregon / USA.  Addition & subtraction  was
working, but multiplication & division was not. After applying WD-40
& appropriate TEST DATA, the clogged gears were freed and the VICTOR
calculator was working ( see above ).

After 3 days of TESTS  the machine fall into  ENDLESS PRINTING ZEROS
like the VICTOR AUTOMATIC-75 and there seems no way to find out why.
After hours  of carefully inspecting the mechanics, a  CLAMPED LEVER
on the left inside was discovered and freed.

More TESTS showed sometimes the first entered figure was dropped ???
After disassembling: The input unit was ok, but the MATRIX was not !
The  FRONT-LEFT PIN  fell randomly down, blocked sensing the entered
figure-pin.  Knowing the difficulties involved in REPAIRING A MATRIX
(s. VICTOR TALLYMASTER ) As a SOLUTION this ZERO-Pin was REMOVED ...

!!! BUT ATTENTION -  Only possible  in this  LEFTMOST  POSITION  !!!
!!!  ASSUMING THAT NO LEADING ZERO IS ENTERED WITH THE NUMBER.   !!!
!!! ( Because a NON-SET matrix-column is recogniced as a "9". )  !!!

More  T E S T S  with  SOMETIMES WRONG RESULTS  raised the QUESTION:

     " Was this  VICTOR-AUTOMATIC-73  a  RETURNED LEMON ??? "

Autumn 2014 ...

  

An "ORGAN-TRANSPLANT" made:  The Error-Matrix was  e x c h a n g e d
AGAINST THE MATRIX OUT OF THE VICTOR AUTOMATIC-75. It took hours ...
Going through LOOPING ZEROS again ...
                                             ... A CHAOTIC HARDWARE!
Winter 2015 ...

... Looking for new errors, a  BENT STUD  (= Part of the input unit)
was detected. In trying to straiten it broke. To avoid disassembling
(= May facing new problems) a  BRASS PIECE  was made  and fixed with
2-Component-Glue ...
    

WHAT NEXT ???

  
  

... BE PREPARED !!!
                      Have a look at Model 75 ( Restoration failed )
