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.
