This was a fun thing to see after having just finished binging Ben Eaters 6502 breadboard computer series.

Since it's printing something out I suppose it also has everything else virtualised, would be cool to be able to provide it some machine code / assembly

I networked a 6502 a while ago in order to capture some behavior that isn't well documented.

You can interact with it using a wasm-based assembler in your browser. Programs only get 100 cycles to run but that should be plenty if you just want to poke around.

How many layers of virtualisation do we need?

Run it in a browser in Wine on a MAC?

None of them run in a browser powered by WebAssembly. I created a 2D engine in C++20 based on SDL, in which I can use Lua to create games. Then I thought, “I’ll make a NES emulator,” so I started with its CPU, the 6502.
