Abstract
1,070,421. Checking arrangements. INTERNATIONAL BUSINESS MACHINES CORPORATION. Nov. 26, 1964 [Dec. 23, 1963], No. 48026/64. Heading G4A. In a cyclically operable computer, a number of error checking circuits are themselves checked during each cycle by application of check test signals which simulate the erroneous signal combinations which the error checking circuits are adapted to recognise, there being means responsive only to an error signal from all of said error checking circuits to set an indicating circuit. The subject matter is included in Specifications 1,070,423 and 1,070,424 which are referred to.
