Ok, Ok, I see from this thread that a *NIX compatible MACH already ported
is going to require an ATT license, at least.  Now for a slightly different
question:

What is necessary to get the 'bare' kernel and port it to your own hardware
with your own system call interface (which might look like POSIX ;-)?
Specifically, I'm working on a parallel processor based on 88000's in a
VME cage, with cages connected in a Hypercube arrangement.  We have an
incredibly primitive executive which load & runs single tasks on each processor.
We would like to get to the next step of having a 'real' executive.

So, I don't need hardware manufacturer code license, I'll write the
hardware interface code.  I don't need *NIX server code (though it would be
nice & I'll probably support 'vanilla' I/O stuff)  I would like to have
a kernel with the capabilities I believe MACH has.  Is there a way to get
just license-free code & some porting documentation?  We are a research
center, we're not goig to sell this stuff.

I'm posting since I suspect I'm not the only one in this situation, I hope
it isn't considered a waste.
