Floppy Days 59 - The HP41C Calculator, Part I, History with Richard Nelson and Gene Wright

Hello, all, and welcome to the next installment of the podcast that says “vintage electronics: I WANT IT”.  I’m Randy Kindig and I’m your host.  This episode is the first of a 2-parter on the Hewlett Packard HP-41 line of programmable calculators.  The HP-41 is a seminal example of programmable calculators from the late 70’s and into the 80’s and is still very desirable and sought after today.  I was lucky enough to find 2 gentlemen to co-host who are well-known among the active HP calculator community that exists today: Richard J. Nelson, who has written, edited, and published as much HP-41 material as anyone ever.  And Gene Wright who is on the HP Handheld Conference Committee and he was a TI fan before becoming “hooked” on the HP-41.  In this first part on the HP-41, I interview the co-hosts and then we cover the history of the calculator line in detail.  Next month, with the same co-hosts, we will cover Web sites, emulation, software, and much more. To start out, as usual, I will cover my new vintage computer acquisitions, a little news, and some feedback. I hope you enjoy this and please let me know what you think.
