In December 1973 Intel shipped the first 8-bit, N-channel microprocessor, the 8080. Since then it has become the most widely used microprocessor in the industry. Applications of the 8080 span from large, intelligent systems terminals to decompression computers for deep sea divers. This 8080 Microcomputer Systems User's Manual presents all of the 8080 system components. Over twenty-five devices are described in detail. These new devices further enhance the 8080 system: 8080A - 8-Bit Central Processor Unit Functionally and Electrically Compatible with the 8080. TTL Drive Capability. Enhanced Timing. 8224 - Clock Generator for 8080A. Single 16 Pin (DIP) Package. Auxiliary Timing Functions. Power-On Reset. 8228 - System Controller for 8080A. Single 28 Pin (DIP) Package. Single Interrupt Vector (RST 7) . . Multi-Byte Interrupt Instruction Capability (e.g. CALL). Direct Data and Control Bus Connect to all 8080 System. I/O and Memory Components. 8251 - Programmable Communication Interface. ASYNC or SYNC (including IBM bi
