As pointed out by a note "provided by Stuart Brook of Mentec" that
can be found on the Dbit web site there was work being done by Mentec
in late 1999 on a potential Hobbyist License for the Software they
somewhat controlled.  At that time there were several very outspoken
members of the community who publicly stated that they didn't care,
one way or the other, whether Mentec made a Hobbyist License or not.
They would continue to use Mentec's IP as they wished.

Shortly thereafter all talk of a PDP-11 Hobbyist License from Mentec
came to an end.
