This information was gathered over 50 years ago when I had my first DX-100. Some of this information was widely distributed but other information was not widely distributed. However, all the information came directly from Heath (when growing up I lived about 35 miles from the Heath plant on Hilltop Road in St. Joseph, Michigan).</div><div style="font-size: 12pt;
