Bob,
Not Andrew but can shed some light on the subject.
the original MDI which stands for Manual Data Input was a weird
machine powered by a Heidenhain TNC131 controller that would only do
linear moves, no arcs or circles.
Aimed at simple repetion jobs like drilling and simple pockets.
this controller then got updated to the TNC135 which was the same but
had a screen.
The Series II came out as a 135 but soon had the 145 fitted to do away
with the linear moves.
The term Interact appeared something around the 145 / 155 controller
change.
Mach 2, now Mach3 is actually a controller like the 145 and unless you
are thinking about gutting the machine then this isn't for you.
What you need is a CAD / CAM package that's capable of outputting
Heidenhain code for your machine.
Take a look at a program called Dolphin at http://www.dolphin.gb.com/
This is one of the cheaper ones that can output to your machine.
