This is what I think is the first version of Mach, for the VAX. The
kernel is buildable, and it just runs on a 4.3BSD userland, which is unaultered. There is refrence to accent scattered around, which was the
OS used before Mach.
This is the Mt Xinu Mach386 userland with the source I was able to find
for Mach 2.5. The kernel does compile. The userland is said to be that
of 4.3BSD Reno, however there is enough drift that rebuilding LIBC just
doesn't work. And all the special disk format/partition tool source is
lost as well.
Does anyone have any of this ancient stuff??
I can't believe that I'm literally the last person in the world looking
for this stuff, and or archiving it.
