'Madix Allesrechenmaschine' was produced by the 'VEB
Feinwerktechnik Dresden,' the former 'Ascota Werke.'
According to the Quality-Mark the production date may be
in circa 1950. As you see, it has a remarkable 10-key-pad
with left and right shift and jump left for division.
Key-location is at the upper row: 2 4 5 7 9 and at the
lower row: 1 3 0 6 8. The register-capacities are: setup
reg: 9 digits, 13 positions; result reg: 13 digits; count
reg: 8 digits with automatic operation recognition. Three
different handles for clearing each register at both
sides. I think, it is the classical 'Sprossenrad
Maschine' (pinwheel ?)."
