This project provides a Visual Studio Extension to develop programs written in Z80 assembly language for the Sinclair ZX81. In particular:
You can assemble Z80 programs without any other external software.
You can debug your programs within Visual Studio Code, stepping, putting breakpoints, etc.
Your program runs in an internal simulator, and the debugger displays a simulated display and accepts inputs from the keyboard.
If you prefer, you can use an external (and more accurate) simulator such as Zesarux.
This Extension is only for the ZX81 computer. If you are looking for an Extension for the ZX-Spectrum, look at DeZog. The ZX81 Debugger is based on this Extension.
