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.

Floppy Days 67 - The HP85B Computer, Part 3, with Everett Kaser and Vassilis Prevelakis

The HP-85B Microcomputer, Part 2 Hello, and welcome to episode 64 of the Floppy Days Podcast, where old computers come to live.  I’m Randy Kindig and I’m happy to bring you this episode this month.  This episode is Part 2 about the HP Series 80 line of microcomputers.  Last month I interviewed 2 well-known members of the HP Series 80 community, Everett Kaser former HP engineer who worked on the Series 80 and runs kaser.com and Vassilis Prevelakis of series80.org.  This month, they are back to help me talk about the history of these fabulous machines.  It’s a fascinating conversation with two gentlemen who have a lot of love of and knowledge about these machines. I want to thank Everett for providing the intro to this episode with his memories of the Series 80. Before getting into the meat of the program, I do intend to talk briefly about any new vintage computer acquisitions, upcoming shows and feedback. Ok, let’s fire up the ol’ HP-85 and see what we can learn.

Floppy Days 64 - The HP85B Computer, Part 2, with Everett Kaser and Vassilis Prevelakis

Welcome to episode 62 of the Floppy Days Podcast, where a little smoke once in a while is a hazard of the hobby.  In the vintage computer timeline, we are still in the 1979 to 1980 timeframe.  This month we are covering the HP-85 desktop computer, or actually the entire series of which the HP-85 was a part known as the HP Series 80. I struck gold when I found the two gentlemen who are co-hosting this episode with me.  First is Everett Kaser, who worked for HP for 20 years and was intimately involved in the development and support of the HP-85.  Secondly, we have Vassilis Prevelakis, who runs one of the best resources about the HP Series 80 in existence today, hpseries80.org.  Once we started talking, and I interviewed the two gentlemen, I realized we were going to need a multi-part show to cover the large amount of information and history around this significant platform.  So, the first show will be the interview with Everett and Vassilis and next month we will get into history, tech specs, emulation, Web sites, and all of the other information I like to cover. Before we get into that, however, I will cover new acquistions, a little news, and some feedback I’ve received.
