R E M A R K TO THE RESTORATION:
-------------------------------------------------------------------
The original power cable was broken on the end of the plug. Cutting
the plug from its cable, freed the wires and found: "Contacts OK".
Now it was decided TO MAKE AN "ANGLE-PLUG", because the calculator
can be better placed near a wall. A half FILM-BOX was used, a frame
made of PERTINAX, and a new power cable soldered to the old plug.
Finally all together is placed and sealed with COMPONENT GLUE:
