TL;DR: In this article, a data processing arrangement having three data processors, each with its own data store and each processing the same information is connected to a majority voting circuit, which gives as an output that output of the majority of the processors.
Abstract: A data processing arrangement having three data processors, each with its own data store and each processing the same information is connected to a majority voting circuit. The majority voting circuit gives as an output that output of the majority of the processors. Whenever a processor output disagrees with the majority verdict above a predetermined disagreement rate an alarm is raised or the particular processor isolated. Also provided is a switch for rendering inoperative the alarm or isolating means until the rate of disagreement falls below a further predetermined level.

TL;DR: In this paper, a memory having circuits for correcting single errors in a word read from the memory is provided with means to reconfigure the memory so that a configuration having a double, uncorrectable, error is changed to a configuration with two single, correctable errors.
Abstract: A memory having circuits for correcting single errors in a word read from the memory is provided with means to reconfigure the memory so that a configuration having a double, uncorrectable, error is changed to a configuration having two single, correctable errors. In one embodiment, interchanging plug-in components for two or more bit positions produces a new configuration; in another embodiment, the wiring to the plug-in components is easily changeable.

TL;DR: The Bell-Rutgers data highway system is a modular, general purpose system designed to provide a framework in which the configuration and reconfiguration of on-line computer hardware is easily accomplished.
Abstract: The Bell-Rutgers data highway system is a modular, general purpose system designed to provide a framework in which the configuration and reconfiguration of on-line computer hardware is easily accomplished. It is built using modified NIM hardware, and features a 16 bit parallel data path for input and output which is shared by up to 150 general purpose modules. Special consideration has been given to two particular problems; the operation of modules in an environment in which digital switching noise must be minimized, and the simultaneous use of the module system by several independent users. The initial application of the system has been in the implementation of a computer based nuclear physics data acquisition and analysis system. The following paper is intended as an exposition of some of the considerations which are relevant to the design of any general purpose modular system as well as a description of a particular system. Some of the ways in which the system has been used are also described.
