Synopsis: This paper discusses the design and application of an advanced magnetic-tape storage system with facilities for automatic access to files as large as 200 million characters with average access times in the 5 to 20 second range. The Datafile System, which employs standard magnetic-tape and recording techniques, also provides an economical solution to many medium-speed random-access problems and avoids awkward and time consuming tape-handling processes.

The National Cash Register Company (NCR) 304 system is a moderatesized electronic data-processor for general business use. It incorporates many new design concepts which result in performance capabilities comparable to those of a large scale system. Each of the features was designed to provide maximum versatility in the handling of business data. The NCR 304 system offers the advantages of electronic data-processing to many organizations that have not yet found it economically feasible.

The DATAmatic 1000 (D-1000) is a high-capacity electronic data-processing system designed specifically for application to the increasingly complex problems and procedures of present-day business. The system incorporates significant new systems techniques, as well as several basically new component developments. One of the outstanding features of the D-1000 is its ability to feed information from magnetic tape into the central processor at a sustained rate of 60,000 decimal-digits per second, and to deliver data after processing back to magnetic tape at this same rate. The operational speed of the central processor maintains full compatibility with the high speed of information transfer. Consequently, the difficulties caused by programs which are either tape limited or processing-time limited do not arise in the majority of commercial applications of this system.

In developing higher speed computing equipment it is generally necessary also to develop faster memory systems which are reliable and efficient, and yet do not have prohibitive costs. This need has prompted many investigations of new materials and new fabrication methods.

Synopsis: A computer component based on the magnetic destruction of superconductivity has been proposed, and an information-handling system involving a large number of such elements is described in a companion paper. In this paper attention is directed toward the electrical characteristics of superconductive components. Also recently measured switching-time characteristics, switching from an energy standpoint, and a comparison of switching in superconductors with switching in magnetic and ferroelectric materials are discussed. A brief description of the component is first given.

Synopsis: This paper considers the application of silicon-alloy transistors to digital-computer circuits, such as flip-flops and gates, suitable for operation at high temperatures. Circuits using the T-1159 silicon surface-alloy transistor will perform at temperatures as high as 140 C (degrees centigrade) with switching times on the order of tenths of a microsecond (μsec). No particular precautions or compensating components are required in order to obtain such performance.
