  Advantage Six A9home

[Advantage 6]     [After Acorn ]


The A9Home is the first RISC OS desktop computer running on a ARM9 CPU, and the only new ARM based desktop computer since the Iyonix was launched in October 2002. It was pre-launched (in beta) to experience users in 2005 at the Wakefield RISC OS Show. In 2006 CJE Micros, also at Wakefield, started selling it to the general public.

The A9Home runs a new 32bit version of RISC OS Ltd's RISC OS Adjust called Adjust32. The version on this computer is still a prerelease (pre8), but it seems stable and almost everything I have tried has worked (except using a Belkin USB KVM instead of the supplied mouse, keyboard and Monitor).

As of March 2010 the final version of the A9Home's operating system has not be released. Some users have reported persistent problems particularly with disc corruptions, loss of network configurations and software incompatabilities. Others seem to be relatively trouble free. I suspect that the delays are because of the lack of expereinced RISC OS developers and the conflicting demands on their time. Hopeful the final version of RISC OS for the A9Home will be available soon.

Benchmarksnote 2


  1. The A9Home is a sealed unit, opening the unit voids the warrentee, which I have decided not to do yet.
  2. Neither !SICK nor ARMSi are 32bit compatible so I can't run benchmarks.
