Boot RISC OS
RISC OS 3.71 — the RiscPC desktop of 1996 — running in your browser. Nothing to install, no plug-ins, and the hard disc keeps what you leave on it.

What is here
The Wimp and its window furniture, the icon bar, the Filer, the Pinboard and the Task Manager, a hard disc that remembers what you put on it, and a BBC BASIC V interpreter. The applications are ports of the original sources: !Draw, !Paint, !Edit, !Chars, !Alarm, !Help, !Configure, !SciCalc, !Maestro, !ChangeFSI and the Diversions games among them.
Open the hard disc and start with $.Docs, which explains what this desktop adds to RISC OS 3.71.
Before you start
- Use a recent Chrome, Firefox or Safari. The first visit shows the boot sequence; later visits go straight to the desktop.
- The desktop wants a keyboard and a mouse, and it uses the Acorn button order, so Menu is the middle button.
- Your hard disc is stored in your own browser. Clearing the site's data empties it.
- Two features need the project's own Node server and so are not available here: !Browse's built-in browser engine, which falls back to showing pages in a frame, and mounting folders from the server. Folders from your own computer still work in Chrome.
