A new browser-based Z80 REPL has been released by abagames, allowing users to write and execute Z80 assembly code directly in the browser. The tool provides an interactive environment for the classic Z80 processor, featuring a code editor, register display, and memory viewer. It supports loading and saving programs, making it suitable for education, retrocomputing enthusiasts, and developers working with vintage hardware.

The implementation runs entirely client-side using WebAssembly, requiring no server backend. The project is hosted on GitHub Pages at abagames.github.io/z80-repl/index.html and the source code is available on GitHub. The Hacker News submission garnered 64 points and 7 comments, with users discussing the Z80 architecture, WebAssembly performance, and potential educational uses.

This tool joins a growing ecosystem of browser-based emulators that lower the barrier to entry for learning assembly language and retro computing.
