Nope, wrong attribute. I can only wish that I was as knowledgeable as you
and the writer on theTRS80 m.II.
 Hey Ward, I see you have a home page. What about hosting a Model II, m.16
6000 page. It would be the only one among a plethora of other TRS80 pages
which Always have a gap in their coverage of Models 1,3,4 , CoCo !,2.3.100,200
Tandy 1000 etc.,etc. The model II orphans would bless you. You're certainly
knowledgeable enough about it coming from a RS background. Tandy only has a
minimal bit of stuff on it re mod.IIs and there's no other source that I've
been able to find.
