The Computron was an electron tube designed to perform the parallel addition and multiplication of digital numbers. It was conceived by Richard L. Snyder, Jr., Jan A. Rajchman, Paul Rudnick and the digital computer group at the laboratories of the Radio Corporation of America under the direction of Vladimir Zworykin. Development began in 1941 under contract OEM-sr-591 to Division 7 of the National Defense Research Committee of the United States Office of Research and Development. A United States Patent was filed 30 July 1943 and granted 22 July 1947 for the Computron.

  • The Computron was an electron tube designed to perform the parallel addition and multiplication of digital numbers. It was conceived by Richard L. Snyder, Jr., Jan A. Rajchman, Paul Rudnick and the digital computer group at the laboratories of the Radio Corporation of America under the direction of Vladimir Zworykin. Development began in 1941 under contract OEM-sr-591 to Division 7 of the National Defense Research Committee of the United States Office of Research and Development. The numerical function of the Computron was to solve the equation where A, B, C, and D are 14 bit inputs and S is a 28 bit output. This function was key to the RCA attempt to produce a non-analog computer based fire-control system for use in artillery aiming during WWII. A simple way to describe the physically complex Computron is to begin with a cathode ray tube structure in the form of a right-circular cylinder with a central vertical cathode structure. The cylinder is composed of 14 discrete planes, each plane having 14 individual radial outward projecting beams. Each of the 196 individual beams is steered by multiple deflection plates toward its two targets. Some deflection plates are connected to circuitry external to the Computron and are the data inputs. The balance of the plates are connected to internal targets and are the partial sums and products from other stages within the tube. Some of the targets are connected to circuitry outside the tube and represent the result. The electronic function of the Computron design incorporated steered, rather than gated, multiple electron beams. Additionally, the Computron was based on the ability of a secondary electron emission target, under electron bombardment, to assume the potential of the nearest collector electrode. The Additron Tube design by Josef Kates gated electron beams of a fixed trajectory with several control grids which either passed or blocked a current. The Computron was a complex cathode ray tube while the Additron was a triode with multiple grids and targets. A subsection of the Computron was prototyped and tested and the concept validated but the building of an entire device was never attempted. A United States Patent was filed 30 July 1943 and granted 22 July 1947 for the Computron. (en)
