Research Unix Sixth Edition (WASM)


This web page runs a Go port of
the Research Unix Sixth Edition kernel,
running user-mode code in a simulated
PDP11 CPU, all compiled to WebAssembly,
executed in your browser.

A few accounts are root, dmr, and ken.
The password is the username.
Have fun poking around.

cd is spelled chdir.

Erase is #, and line kill is @.
As a convenience to 21st century users,
typing backspace and ^U generate these.

Echoed terminal input appears in bold.

The simulator runs in the browser UI thread,
so long computations block the browser UI.

On mobile devices, clicking a tty button
should bring up the keyboard,
but scrolling to the output point seems broken.
Patches welcome.
