Hello, and welcome to episode 152 of the Floppy Days Podcast for June, 2025.  My name is Randy Kindig and I'm the host for this lovefest for vintage computers and programmable calculators from the late 70's thru the 80's.  If you love old computers, you've found the right place!

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.
