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.

Boot RISC OS

The RISC OS 3.71 desktop with a Filer window open on the hard disc and the Filer menu showing Display and sort options
The Filer and its menu, on the Acorn tiled backdrop.

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.
