This paper introduces a Z-80 microprocessor-based development system based on Apple II and its compatible personal computer.The system includes a hardware module of Z-80 in-circuit emulator relying on Apple II microcomputer and the corresponding control software. The emulator adds a microcomputer development capability to the Apple machine, increasing the utilization of the existing microcomputer and improving the development of a Z-80 microprocessor-based target system. The target system can borrow the memory of the Apple machine through the emulator , Peripherals and other hardware resources.The system uses CP / M operating system, which has a wealth of software, the target system for software and hardware integrated debugging.
