Correct. Although nobody can pay the latest developments.
Look at the R4000PC. Only *one* year ago it was around $2000,
now it's at about $600...

Don't know. This depends on how complete the NEC ARCset is. So far I
know solves it most of our problems. In case it is true that the
ARCset is a *complete* design, we would only have to make some
changes to satisfy the requirement of the group. Perhaps we have to
make no changes at all !

Neil made the assumption that it will take a bit more than half a man-year
to port the kernel and drivers. This depends on how many filesystems we will
support. For me, ext2fs and the ISO fs would be enough.
Everything else *should* compile out of the box, except the X11-server stuff.
That sounds not too bad, isn't it ?

I can't say how long it takes to make the hardware working, because it
depends on what we want.
