This month, I'm completing the ongoing series of episodes about the HP 97/67 programmable calculators.  This is the third and final in the series that provides us with a terrific co-host who is able to provide a lot of color about these machines: that being HP calculator historian Wlodek Mier-Jedrzejowicz ("Vwahdek Meer-Yeng SHAY of itch").  No one knows more about HP calculators than Wlodek and all of us are honored to get his insight into these HP calculator gems.
