REMARKS:
========================================================================
Subtraction has to be performed as 9-Complement "Addition" (s.BURROUGHS)

The lenght of the paper can be pre-set to activate a bell at its end.
To change (fixed) columns, the carriage has to be flipped into position.

The ribbon spools from bottom to top only - The bottom spool device was
missing - A temporary spool was made out of a plastic cylinder - Than
the re-spooled ribbon was mounted by wire in the bottom of the machine,
