As an experiment, I gave the source zip file to Claude and told it to make a WASM version of the app, by translating the Pascal to Go.

It nailed it, first try.

I cannot, unfortunately, share a link to the website it created because of the license.

LLM translations of historical software to modern platforms is a solved problem. Try it, you'll see.

I used https://exe.dev/ and their Shelley agent to drive Claude. Give it a try, it is jaw dropping.
