Abstract

In the present-day text or word processing environment, the operator often requires access to a host data processor through a low cost data link for data processing and records capability. An original solution to this problem was to utilize both a text processor and a separate data display terminal, such as the IBM 3278, which was compatible with the data processor. However, with the integration of data processing and text processing capability into an overall office systems environment, the field is advancing in the direction of utilizing the display terminal associated with the text processing system as an output terminal for the host data processor.

Interface Module Between a Word Processor Emulation of Data Processing Display and the Control Unit for a Host Data Processor

In the present-day text or word processing environment, the operator often requires access to a host data processor through a low cost data link for data processing and records capability. An original solution to this problem was to utilize both a text processor and a separate data display terminal, such as the IBM 3278, which was compatible with the data processor. However, with the integration of data processing and text processing capability into an overall office systems environment, the field is advancing in the direction of utilizing the display terminal associated with the text processing system as an output terminal for the host data processor. In such a system, operator interactive capability is provided for switching from a text processing session to a data processing session wherein the text processor emulates a data processing display terminal. The present apparatus provides an interface between the control unit for the host processor and word processing system. Such an interface must interface with the memory associated with the processor controller as well as the input/output decode circuitry of the processor controller. The decode module, shown diagrammatically in the figure in terms of its input/output pins, serves as an interface between the word processing system bus and generates all the signals necessary for the word pr...
