AI one-shots a complete Hello World app for a 34-year-old Macintosh Plus

Reddit user Detz reports that the AI coding model Sol 6.1 one-shot a fully working Hello World application for a 34-year-old Macintosh Plus, with no iteration needed.
The generated C code uses the classic Macintosh toolbox APIs (Quickdraw, WindowPtr, EventRecord) and correctly implements:
- Window creation and centered text drawing
- A File menu with Quit item and Cmd+Q shortcut
- A full event loop handling mouse clicks, window dragging, the close box, and keyboard events
The impressive part is the model's command of legacy quirks — Pascal-style string constants, classic Mac OS memory and event conventions — producing code that compiles and runs on ancient hardware on the first try.
