Payroll accounting with Elecom 120 computer

Abstract

The Elecom is a magnetic drum computer of the same general type as the Elecom 100, which was described in detail by Mr. Auerbach of this company at the meeting of the Association for Computing Machinery in Pittsburgh last May, and published in the Proceedings of that meeting. It differs from the 100 in two important respects; operation is decimal throughout, and the memory capacity has been increased from 512 to 1000 words. The change from binary to decimal operation results in a machine which is well adapted to commercial applications as well as purely mathematical computations.
