The Z80 Microprocessor Kit is designed for self-learning how to program the Z80 microcomputer with Z80 machine code. The design concept uses a small number of chips, only CPU, ROM, RAM and cheap I/O ports using CMOS latch and buffer IC. The monitor commands are compatible with MPF-1 board plus additional HEX file upload/download commands. The 8-bit dot LED is designed for displaying 8-bit binary number directly. Under program testing, it will be used to display the contents of accumulator register. The microcontroller, 89C2051 provides 10ms system tick. It can be used for time trigger event. The kit is suitable for self learning the basic of today\'s computer with low level programming by HEX code. The software UART, 2400 bit/s allows Intel hex file downloading. We can also play with sdcc c compiler that generates Hex file. Hardware features:
