The VS Code Skeleton
Building a debugger means implementing the Debug Adapter Protocol. For Debug80, I chose an inline implementation to keep the connection between the interface and the machine model as tight as possible.

Listings, Mapping, and Making Execution Legible
Debug80 treats assembler listings as primary data and uses them to build explicit mappings between source code, addresses, and runtime execution.
Debug80 as a System
Debug80 integrates a JavaScript Z80 assembler with VS Code’s debugging infrastructure to create a coherent environment for building and observing Z80 programs.
The TEC-1 as a Platform
The TEC-1 defines a small but complete hardware platform. Its memory map, I/O model, and human interface provide a concrete starting point for Debug80’s platform system.
Why I Came Back to the Z80
My work with the Z80 began on paper in the late 1970s and became real hardware in the early 1980s. This series documents a return to that architecture through the construction of a modern debugging environment.
