The HP Series 80 (HP83/85/86/87)

This episode is the third and final in a series about the Hewlett Packard HP-85 computer, or more accurately, the entire line of similar computers known as the HP Series 80.  Once again, I have the tremendously knowledgeable duo of Everett Kaser and Vassilis Prevelakis helping me impart information to you about that venerable line of historically significant desktop computers.  In this episode, we will primarily be covering tech specs, peripherals, expansion, magazines and newletters, books, emulation, modern upgrades, connectivity to modern computers, buying one today, community and Web sites.  Wow, now that I list this out, it’s obvious we have a lot to cover.  In addition, I will briefly talk about my new vintage computer acquisitions, feedback and perhaps a little news.

Welcome to Episode 66 of the Floppy Days Podcast, where we try to relive our youth by talking about computers nearly as old as we are.  Vintage Computer Festival Midwest #11 recently happened on Sep. 10 and 11, 2016 in Elk Grove Village, IL and I managed to find my way there again this year.  Once again, I had an incredible time at the event and thought I’d share some of it with you.  I managed to get a few interviews, meet several people I had never met before, catch up with old friends, and come home with far more items than I left with.  So, I plan to give you a quick run-down of the event through my eyes and I hope you find this interesting.
