[ASM80](https://beta.asm80.com) is a free, browser-based cross-assembler, emulator and debugger for classic 8-bit CPUs (Z80, 8080, 6502, 6809 and others). Key features: - Multi-CPU support in a single environment - Built-in emulators for real machines (ZX Spectrum, TEC-1, etc.) - Integrated debugger with step-by-step execution - Online project management — no installation required The assembler core is open source under MIT license: https://github.com/asm80/asm80-core ## Why does it belong here? It fits naturally alongside similar tools already listed, and is directly useful for anyone doing retro 8-bit development. --- README.md | 2 ++ 1 file changed, 2 insertions(+) diff --git a/README.md b/README.md index ab0ba9b..1b1b9e2 100644 --- a/README.md +++ b/README.md @@ -326,6 +326,8 @@ Targets over 80 different machine families. * [zmac](https://github.com/sehugg/zmac) - Macro cross-assembler for the Zilog Z80 microprocessor, sometimes used for Astrocade development. +* [ASM80](https://beta.asm80.com) - Free browser-based cross-assembler, emulator and debugger for classic 8-bit CPUs (Z80, 8080, 6502, 6809 and others).
