"This paper describes the interface between the NOVA digital computer and the Texas Instrument tape unit which handles field data recorded simultaneously from a maximum of 31 channels. The interface is the means through which the NOVA computer can control the tape unit and recover data. To provide necessary background information a review of the characteristics of the tape unit and the input-output operation of the NOVA computer are given. As the first part of the design, the general interface design is presented and the functions of its units are described. After discussion of functional assignment of each unit, coordination between them is discussed on the transfer level so that the Boolean equations describing the interface operation can be derived.
The interface can run the tape transport in forward or reverse to find a desired record. It can select the data of any specified channel in any desired record from some specified point in the record. The flexibility of an interrupt system is available for the data processing"--Abstract, page iii.
