01/04/21 - VirtualAcorn website overhaul

Here at VirtualAcorn there's one thing that drives us mad (well one thing about other people's websites that drives us mad) and that's broken links. Missing content and links that point to holding pages or nowhere are a menace, especially when the pages concerned have instructions you really do need right now. That's what happened to us a couple of months ago and apart from the gnashing of teeth there was also a little nagging voice in the back of the mind saying 'When did you last check all the links on more)

About VirtualAcorn

Virtual Acorn allows you to run the Acorn operating system RISC OS on a Windows PC with Windows 2000, XP, Vista, Windows 7, Windows 8 or Windows 10. You can also run RISC OS on a G4, G5 or Intel Mac with Mac OS X 10.4 or later. Any RISC OS programs can then be run on the PC/Mac. VirtualAcorn can operate inside a window, just like any other Windows application, but can also run full screen. In full screen mode the PC looks and feels just like an Acorn computer. VirtualAcorn requires no extra hardware to be fitted in your PC and can be installed in minutes.

Every copy of VirtualAcorn comes with appropriate software and documentation including:

  • An appropriate version of the Acorn RISC operating system.
  • Complete HTML RISC OS user manual with EasyStart front end.
  • Virtual ADFS hard disk drive with the latest !Boot sequence.
  • Facility to read Acorn floppy discs and CD-ROMs.

VirtualAcorn really is the best of both worlds. You can run the operating system you want, RISC OS, on cheap fast modern hardware. Why have two computers, when you can have everything you need in one?
