Hi Dave
 I have a couple of Horizons and a older style box ( no wood ).
I've not had time to fiddle with these but I think the Horizons
use the double density controllers. Right now, I'm still fiddling
with the H8 machines but the N* was on my list of machines
to create a transfer program for. It sounds like you have already
done the work here.
 None of my machine have been powered on since I got them ( at
least 2 or 3 years ). It'll be fun turning them on and watching
the smoke.
 I think I have some disk with these but I've not looked to
see what I got. Projects, projects and more projects.
