Z80 REPL: An Interactive Environment for Zilog Z80 Assembly

The Z80 REPL is a browser-based interactive development environment designed for the Zilog Z80 microprocessor architecture. This tool allows developers and enthusiasts to write, assemble, and execute Z80 assembly code directly within their web browser. By providing a Read-Eval-Print Loop (REPL) interface, it simplifies the process of experimenting with low-level assembly instructions, register manipulation, and memory management without the need for complex cross-compilation toolchains or physical hardware. The project serves as an excellent educational resource for those interested in retro-computing, embedded systems, or understanding the foundational architecture of 8-bit microprocessors. Users can test small snippets of code, observe the state of registers in real-time, and gain a deeper understanding of how machine-level instructions interact with the CPU. This lightweight, accessible platform lowers the barrier to entry for assembly language programming and provides a convenient sandbox for testing Z80-specific logic.
