Well you can buy them new AFAIK, but in terms of technology, you can
only add "old" StrongARMs. It won't be worth the price of a new one
though, try to buy one that already has a StrongARM.
If you're thinking of the XScale-based ones as used by Iyonix, they're
incompatible. In theory I expect an upgrade would be possible, but I
think the concenus is that it isn't worth designing one because it would
be too badly throttled by the Risc PC bus.
They could just about keep up with contemporary PowerPCs and Pentiums.
But that was about 6 years ago... And only for integer operations.
For anything using floating point (FP) they're desperate.
I've got a feeling RISC OS 3 is limited to 2GB, but RISC OS 4/Select can
see 30GB+ OK
A lot slower than the StrongARM. You won't notice it much just rummaging
around RISC OS's GUI, but if if you try doing anything
processor-intensive like compiling, photo editing, ray-tracing, number
crunching, MP3-encoding or even viewing a complicated web page, it's
going to be a bit painful.
In fact I'm not even sure they can decode MP3s in real time, whereas
that uses less than 1% of a modern x86's power.
It'll be good fun if you've got a spare hundred quid or two, but if
you've got a decent PC why not try Virtual Acorn instead
