Marchant Model 8DRX Calculating Machine - Figurematic


This full-keyboard, non-printing electric proportional gear calculating machine is blue and gray with a metal frame and mechanism, plastic keys and cover, a cloth lining for the frame, and rubber feet. The eight columns of green and white keys have nine keys per column. A column of ten gray keys on the right allows automatic multiplication. Eight wheels display the number entered. Function keys are for addition, subtraction, division, stop, non shift, NEG X, carriage movement (to the right and to the left), and clearing (four keys).

On the carriage at the back are eight wheels for the revolution counter and 16 wheels for the result. Decimal markers slide between the entry and the result registers. Reversible decimal markers turn between windows of the registers on the carriage. The carriage also has a wheel for selection of carriage position.

Inside the case is an electric motor made by General Electric.

A metal tag attached to the bottom of the machine reads: 8DRX-426300. A mark below the keys reads: MARCHANT fIGUREMATIC. A mark on the right and left sides reads: MARCHANT.

The machine was given to the donor by an insurance company employee named Williams.
