Hi.  You can find the OpenBSD 2.0 binaries for the 68k-based macs in the
'tars' directory.  The distribution kernel in the 'kernels' directory
won't function with NetBSD binaries, nor will such binaries work with
the OpenBSD kernels.

Everything you should need to install the binaries, make a filesystem,
and boot the operating system from the MacOS side are in the 'utils'
directory.  The installation procedure is in all ways just like that
of NetBSD/mac68k.  

Hopefully, a specifc INSTALL document will come out for OpenBSD.

In the meantime, enjoy,
