Description

Two-species adder segment printing machine
Brunsviga G 89 (1954)
The model G 89 presented here is the version produced from 1954, which differs from its predecessors primarily in terms of the housing. The machine also subtracts below zero and was built until 1958. After the union with Olympia in 1959, Brunsviga adding machines were no longer manufactured. The function keys on the right effect the subtraction, numbering (not calculating), the subtotal and the final total with deletion of the totalizer; With the small lever, the feed can be set in one or two lines when printing. On the left is the button for repetition, which allows a makeshift multiplication, and the lever for deleting the pen carriage (input value).
