===========================================================================
The calculator was found in an Antique(=Junk-)Shop in PORTLAND, OREGON/USA. 
NOTHING WORKED !!! To find out if it is worth the way to Germany, I applied
"1st-Aid-Maintenance":  Basic cleaning, cleared the locked gears,  restored
motor wireing, ... Finally it runs again!  Because this "MODEL-1" should be
A PRESENT ( WITH FUN ! ) to an expert friend, I stopped further work on it.
