PDP-11 machines (or pages containing PDP-11 machines) can now be marked with a resume property that will (like PCx86 machines) use your browser's local storage to save and restore the machine's state.

For example, if you start this PDP-11/70, load a different disk in the RK0 drive, such as the "RT-11" disk, boot it, make changes to the disk, run programs like ADVENT, and so on, all those changes should be restored when you visit the page later. The PC8080 machine running the VT100 Terminal simulation also supports save/restore, so the contents of the display connected to the PDP-11/70 should be saved and restored, too.

It's entirely possible there are still a few bits of machine state that are not fully preserved yet, but if it's not perfect, it's certainly close.
