microsoft/gw-basic ? reverse-engineered prompt

Build me a simple read only explorer for the original 1983 Microsoft GW BASIC source code in this repo. I want it to feel like a small museum style app where I can browse the files, search through them, and click into each one to see a plain English summary of what it seems to do. It would be great if the app groups things into understandable areas like startup, interpreter logic, math, keyboard, screen, disk, printer, and other system pieces.

Please add a short intro that makes it clear this is a historical source release, that the repo does not come with build scripts, tools, or ready to run binaries, and that the original source files should stay untouched. If possible, include a simple overview page showing how the major files appear to fit together, plus a notes page about what would likely be needed to rebuild or study it on a modern machine.

Keep it easy to run locally, and look up any background docs online if you need to.
