A slightly different approach for aged Apple devices is taken by Joshua Bell. Instead of emulating the entire machine, Joshua limits himself to the emulation of AppleSoft BASIC.

Again, the implementation in Javascript ensures, that you can run your own BASIC source directly and easily in the browser. Performance is no problem.

A whole series of example programs can be loaded, inspected and executed directly. You can load your own experiments from and write them back to disk.

It is amazing how well BASIC can still be used for programming today. However, it is questionable how complex the results can be at most. Anyway, a fully functional project with real added value.
