ACUBE SAM 440/460


During 2006 and 07 the AmigaOS4 had a very tough life, just when AmigaOS4 was evolving into a stable operating system, Eyetech pulled out of the Amiga market, this left the Amiga community struggling to survive on the few AmigaONE machine that had been made, also these boards proved unreliable so a new solution would be needed, due to the contract between Amiga Inc and Hyperion, Eyetech was the only official hardware company allowed to develop new hardware for the AmigaOS, this lead to a legal battle between Amiga Inc and Hyperion for the next 2 years over what hardware the AmigaOS could be allowed to run on and who actually owned the OS. Hyperion partnered with Acube to distribute the AmigaOS 4 software, at the same time they announced a new PPC motherboard, named the Sam, there was much speculation as to weather or not it would run the AmigaOS. At the end of 2008 we had the answer, AmigaOS4 would support the Sam440ep. This was very good news as it finally gave the Amiga new and reliable hardware for the AmigaOS to be sold on. Soon followed where overclocked version of the Sam440ep, many claimed the Sam was underpowered for OS4 at just 533mhz, being less powerful than most Eyetechs AmigaONE systems. There was also calls for more expandability options, as the original Sam440 only featured one PCI slot, most people where using this for a better graphics card than the integrated one that came with the system. This lead to the Sam440ep flex which offered three PCI slots and was sold with a higher clock rate by default, offered more Ram options and was ever so slightly cheaper, both system supported the newly released AmigaOS 4.1 and have become the main stream systems used by Amiga users for developing and using the AmigaOS. In April 2010 it was announced another new Sam motherboard was in development, this would feature a faster processor, running at 1Ghz, offer PCI express and SATA2 connection. This is due out in September and should offer a good middle range and cheaper alternative to the new AmigaONE X1000.

The Operation System

All the Sam motherboard are fully supported by Hyperion AmigaOS, the OS performance on the system has been one to raise question on how good the system are, however a number of update and over clocked systems has improved the performance on the original Sam440 boards. AmigaOS was not the first OS on the system however, a port of Debian Linux also has been made available for the machine, as well as dual booting support for people wishing to run both Linux and the AmigaOS. AROS an Amiga inspired OS was also ported to the machine and has had continued support, it is not know weather AROS will support the SAM460 however due to the similar hardware this would not be a huge task to do so the chance are pretty good of this happing. Its very likely in the foreseeable future any future versions of the AmigaOS will be supported on the Sam systems, it is not known however if there is any plans to allow the Sam to support Xmos chips, a feature that will be found in the AmigaONE X1000.
