you can import any m2 procedure in o2 and vice versa with xds seamlessly.

Not strictly; some russians ported it to AVR.
http://svn.assembla.com/svn/oberonru/trunk/

but maybe there's more, - because why did NW rewrite the O07
(oberon-system (A2?) ARM cross) compiler source in O07?
(O07 is not backward compatible with O[-1]
and I don't assume he's running this compiler on ARM.)

"After defining the Revised Oberon called Oberon-07 and implementing it, I have expressed the
compiler in the revised language."

Just an exercise?

Guess one could port the oberon system to a www.beagleboard.org (anyone?)
but I doubt it runs on a helicopter - at least not while it's flying :)

Everybody who wants to know how generating efficient code and a small compiler
come together - simplicity by design aka implementation restriction - should read this
entirely:

An Oberon Compiler for the ARM Processor, Niklaus Wirth, 18.12.2007, rev. 16.4.2008

If I remember correctly, back in the 1970s when NW created Pascal,
he was called bean-counter by fortran and other hackers and 'real' programmers.
Looking at his latest paper, that seems a big understatement. :)
