Accounting Machines

NCRs first Accounting Machine in 1921, was the 2000, an adaptation of the Class 6000 Cash Register.

which was produced in numerous forms as charge posters, bank proof and accounting machines as well as cash registers. Except for the war years, it enjoyed continuous production until 1973. In the late '50s variations of the 2000 and other models were coupled to paper tape punches to generate computer input.


This was followed by the Class 3000 which was introduced following the acquisition of the Ellis Adding-Typewriter Co. the Class 3000 accounting machine with typewriter was added to the product line in 1929.
