NumWorks open source calculator

[JDW]

My first HP was the 28S I purchased in 1989 when I entered engineering school. I later purchased a 48GX and FRAM card and a 50g. I still use all the calculators as an electrical engineer. Some may call me a collector in that I have 3 top end HP calculators (top end in their day), which even most geeks don't have. But I still am practical. So while I appreciate the explanation, since it isn't something practical, it is not something that would compel me to try it. Thank you for explaining though.
