SNAPSHOTS OF THE NUMERIA 8213 RESTORATION
The calculator came dirty, rusty, damaged & with an
electrical "ShortCut" due to detoriated insulations ...
... Picture taken after 5 hours of "First Aid" Maintenance - "WOW!"
PASSING the ( 7037037037 * X ) TEST - But there is a lot of work ahead!
(1st) Replace the BROKEN SIDES of the carriage ...
... Made TEMPLATES and the NEW SIDES out of PVC sheets ...
(2nd) BOTTOM ( seen rear/down - hole for 110/220 V switch )
The rubber of the SHOCK-ABSORBERS, ROLLER and FEET was
decayed and the old "quick-fix" (right) was broken ...
New solid metal constructions were made ...
( look inside ... outside look )
... and again: FEET made from TUB STOPPERS !
(3rd) Got rid of the inner RUST by rubbing paper-towel
pieces, soaked with WD-40, on the levers & surfaces.
Now the assembled calculator is back to life ...
