Tabulating Machine Component, Control Panel for an IBM 403 Tabulating Machine

Description:

By the late 1940s, the calculations and printout of IBM accounting machines were determined by setting a plugboard like this one and then feeding in data punched on cards. This control panel was used specifically in an IBM 403 tabulating machine, a device introduced in the late 1940s and distributed at least into the late 1960s.

The object has a rectangular metal frame with a metal handle on one of the long edges. It is divided into three sections, each containing a plastic circuit board with numerous holes. Many colorful plastic and cloth-coated wires are plugged into the holes. The board is wired for calculating invoices.

A red tag attached under the handle reads: 403 INVOICE. A tag glued under the panel reads: MFG. BY (/) MAC PANEL (/) COMPANY. This tag also reads: HIGH POINT (/) N. C. and: TYPE 913. A mark stamped at the bottom of one circuit board reads: TYPE 402-403 22573 PRINTED IN USA.

According to the company website, MAC Panel Company was founded in High Point in 1958.

This example came from a programmer who worked with punch card equipment and computers from 1940 until 1985.
