HOW TO USE the ALLEN MODEL 66
*****************************

ADDITION:

Everytime a number is entered and the handle is pulled, the number
is added to the memory ( = DISPLAYED as SubTotal ), printed, and
the keyboard get cleared.

RESET KEYBOARD:
---------------
If a wrong figure is entered in a column, repeat with the right
figure. To clear the keyboard: Press the right red (COR) key.

REPEAT:
-------
To enter the same number more than once, press & push the right red
(RP'T) key before pulling the handle. The keyboard will not be cleared
after releasing the handle. To release the (RP'T) key: Press & pull.

Subtraction:
------------
Only  ADDITION is performed.  For SUBTRACTION 9-Complement "Addition" has
to be used.  ( For  DETAILS  see the INSTRUCTIONS to the  BURROUGHS ... )

SUBTOTAL:

The black key (SUB/TOTAL) IS LOCKED - Before using (SUB/TOTAL) the
handle has to be pulled to make a LINE FEED on paper.
The cumulated sum will be printed ( in RED ) when (SUB/TOTAL) is

REMARKS TO RESTORATION:
=======================
                "How to open the calculator" see WORKSHOP (C):  ALLEN-95

The calculator came dirty & locked.  After intense cleaning, WD-40 (1st) &
(2nd) Silicon Oil application, benting levers, ... it worked again -  BUT:

The rubber knob ...       

of the  PAPER TRANSPORT  was detoriated  and could be replaced  by a black
PLASTIC CAP. Half of the  BLACK KEYS  were detoriated also - But lucky I'm
the  "Spare Part - ALLEN-95"  could be used as a donator for replacements.
There was a "3" missing, but an "8"-Knob was used and half blackened.

The red/black ribbon ...  

is a "Standard" one, but it had to be respooled on the ALLEN-SPOOLS.
