Hmm, Yes, I agree with you, that the Mac and the Atari development are
coupled quite closly together from what I read on the src-changes list.
But the Amiga is the most common m68k-plattform in use for NetBSD and
it does NOT have any FPE emulation built in, i.e. it is not possible to
boot NetBSD on an Amiga without FPU. Thus your work is shared beween
Mac and Atari, but not the Amiga community. Therefore I was not wrong
or incorrect as you say :-)

I agree qith you that some parts are shared between the ports, but there
are a lot more things which the ports have in common, for example some
of the device drivers. I seecomments on the src-changes list like
Mac: taken 5380-driver from Amiga and modified ...
Atari: taken 5380-driver from Mac and modified ...
Mac: Using MI-5380-driver now ...
Amiga: Modified 5380 driver ...
In pratice all ports should be using the MI-5380-code, but only some
of them are actually doing so :-( I'd really like this development
more coordinated and I'd like your code living in /sys/arch/m68k and
being used in all m68k-ports, really! :-)
Thanx for responding and keep up the great work :-)
