"This thesis is concerned with the general operation of the Kennedy Model 1400R incremental write/continuous read magnetic tape unit and the hardware design and software implementation needed to make it compatible for use with the Data General Nova 800 mini-computer.
The hardware design was developed around a General Purpose Interface Board which provides a standard set of logic needed for interfacing any external device to the Nova. The hardware consists of decode networks, mode selection networks, and I/0 timing networks. Special circuits needed to implement the hardware design and perform voltage conversions between the tape unit and the Nova computer are included. The complete hardware design utilizes TTL Integrated Circuit logic.
A software package was written in Nova assembler language which allows the user to write programs or data on magnetic tape and be able to read the programs or data off the tape when needed. Portions of these programs are discussed in this thesis.
The result of this hardware design and software implementation is a device by which faster input and output can be obtained"--Abstract, page ii.
