Default Mapping software problem. How to build .twf (geo-location) into ascan of the right map?

I'm not sure I understand the task entirely, but you might try
MapWindow, it's opensource and free. Pretty powerful really, for the
novice GIS'er. Some useful plugins are either free or cost a minimal
fee, including many different georeferencing tools. JeoPeg Manager is
free, that may work for you depending on the file format of the
Michigan chart.
