S N A P - S H O T S  from the PROCESS of RESTORATION
****************************************************

View into the open back side ...



... The machine came with a "quick & dirty fix" of the power cable.
( Probably the original cable or the plug or both were crumbled. )

A fixed cable is an obstacle in the process of restoration.
To install a MODERN PLUG, there is a HOLDER to construct first ...



... Then the plug get fixed in the holder with component glue & screw
and mounted on the motor block with existing bolt, nut & screws ...



... The picture shows also:
A PLASTIC CAP WITH GRIPS is mounted on the motor axle. This is
necessary for MANUAL OPERATION of the machine to find out
their mal-functions. The base got a new cut-out for this cap
and the existing cut-out has to made broader for the new plug.

Also the COVER has to get a broader cut-out ...



A T T E N T I O N
There is a "SAFETY BREAK" associated with the PAPER/RIBBON-LID.
To work with the open machine, the BROWN LEVER has to be hold down -
here with a BUNGEE CORD ...



To have access from all sides ( and to have space around all gears !)
the calculator is lifted (1st) with its own feet screws ...



... and (2nd) ...



... a frame was made for its support to have access
also from below - when placed between (e.g.) two chairs ...



Status at Xmas 2009:   Machine is printing endless ZEROs.
There was a short time intervall when ADD/SUB was ok, but as
soon the MULT was tried, the machine fall back into ZERO looping.
...
In 2010 - together with a friend - we invested another day ...
... NO SUCCESS ...
SORRY - WE GAVE UP TRYING TO REPAIR THIS CHAOTIC HARDWARE !!!
( ... We will use it as a spare-part donator ... )
