Thanks to Bert Kiers, the source to NetBSD 0.8 has been located!
Currently it resides at http://netbsd.itsx.net/netbsd-0.8-src.tgz
I haven’t tried to build it yet, but I would imagine that it should be possible from either 386 BSD 0.1 with all the patchkits installed, or maybe from within NetBSD 0.9 …
I don’t know if the install diskettes are easily generated… So this may be a source up/down grade depending on how you look at it.
But this is a ‘good thing’ as this would be the last ‘lost’ version of NetBSD. Then I can tackle 386 BSD 0.0 & FreeBSD.
