An Analog Speech I/O Channel for the Nova 2 Computer Based on the S-100 Bus

摘要

The requirements for a capability to provide easy sampling, digitizing and storing of analog speech and video signals to which new hardware and software enhancements can be made without a large investment in resources are stated. A complete discussion of how the AFIT Speech Lab's Cromemco Z-2, Z-80, S-100 based microcomputer system is utilized to meet there requirements by serving as an I/O channel for the Lab's Nova 2 minicomputer is presented. The discussion includes detailed descriptions of the hardware developed to connect an 8-bit system to a 16-bit system, the development of the I/O channel communication protocol that allows the two computers to communicate, and the operating system software that provides the control function for the two computers.
