- Provides the reader with a basic understanding of the inner structure and operation of the TRS-80 Color Computer, its major LSI components, and its expansion capabilities.
- Explains the carious features of the 6809E microprocessor-the central processing unit of the TRS-80 Color Computer.
- Shows how the three fundamental interfacing functions-decoding, three-state buffering, and latching-can be performed using digital logic design techniques.
- Describes how to use a programmable interface adapter (PIA) to develop a simple parallel input/output interface for the TRS-80 Color Computer expansion connector.
- Covers digital-to-analog (D/A) and analog-to-digital (A/D) converters and shows how these devices can be connected to the TRS-80 Color Computer to monitor and control external events.
- Presents six practical experiments in the final chapter designed to demonstrate the material presented in the preceding chapters.
- Contains three appendixes of reference material covering number systems and computer arithmetic, a review of digital logic circuits, and manufacturers' data sheets on the 6809E SPU, the 6821 PIA, the NE5018 D/A converter, and the ADC0804LCN A/D converter.
