JGZimmerle>"You would expect limited expandability from such a machine. And in contrast to the Iyonix, the CPU is upgradable. "

and Jaco>"Theoretically you could upgrade the Iyonix CPU (With CPUs on a PCI card but there's no support)...however you can not replace the CPU of an Iyonix as that is soldered to the board. "

Notionally you can upgrade the A9Home's CPU and RAM, I'd point out currently the version supplied is the fastest available. There may also be limitations on the level of upgrade that might (even theoretically) be possible - for example does the CPU card offer a 32bit or 64bit databus (if not 64 it either won't support xScale or will require further glue logic and a performance hit). There's also the *cost* factor, if the cost of the add on is such that the machine becomes as expensive as an Iyonix you'd be wiser buying an Iyonix !

Also in some instances (as Jaco said) some upgrades are theoretical and remain so (the much vaunted 1GHz xScale that fits to the Omega springs to mind ;).

Yes the Iyonix is limited in that the CPU can't be upgraded, neither is the A9 upgradable at the moment (and the available upgrades may not lift it above the Iyonix in performance terms in any case). In it's favour the Iyonix has genuinely useful features like *currently* being able to take 1GB of RAM (8 times that of the A9) and being able to host 4 IDE devices and have more add on's than you can shake a stick at. So in applauding the acchievement that is the A9 let's not go knocking the Iyonix it still is the "gold standard" of RISC OS computers....
