Oh yes, indeed. And after this one, which seems like a "quick job", I
may get the opportunity to go after an ND-5/0/00/000. The ND-10 is to
the ND-5/50/500/5000 as the PDP-11 is to the PDP-10! Better get the -10
done with, then! :)

It is my goal that it will be, but I can't promise you anything yet.

There is no documentation for the machine, but I was very fortunate to
get in touch with Johnny Oddene.
