z80 vs Python

Oh, it's not a 286 processor, it's a Intel XScale® PXA255, which is a
full 32 bit ARM architecture.  Basically, it's the same processor you
find in a lot of PocketPC PDAs.  So it's not x86 compatible, but there
are plenty of linux versions (full 32 bit) around for it.  Although
the memory constraints require you to scale things down a little.  It
looks like they're taking the processor and adding the minimum support
chips to keep the board small.

It's kind of a shame in some ways, what I'd really like to see is
something using the new multicore ARM, so that you could go for a
massive multiprocessor architecture with the lowest possible power. 
And a higher speed interface, like PCI, so you could gang them
together to a normal pc, kind of like the clearspeed processor
(www.clearspeed.com).  Then you could really start looking at massive
computing power on the desktop at low power.  Not that I really need
it or anything, but still, could be fun.
