I have already spent some time in trying to port Oberon to Intel Macintosh,
but without success so far. The problem is that I can't get the interface
between Oberon code and Darwin working right. Some library funtions
(e.g. printf) do what they should but others (e.g. dlsym) crash with
segmentation violation when they get called via Oberon procedure variables.

Looks like in addition to the right parameters some special machine context
is needed for the failing library functions. Unfortunately I miss a description
of the 'binary application interface'. Until now I havn't found one int the
net.

The PowerMac port of Oberon will not work with Rosetta. Rosetta can only
handle 'finished' programs. In our case the boot loader and the prelinked
core modules. But the Oberon module 'Modules' will fail because it doesn't
know that it is working on a little endian machine.
