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.

Welcome to Episode 65 of the Floppy Days Podcast, where a summer computer camp for middle-aged geeks is the highlight of our year.  My name is Randy Kindig.  This is a very special edition of Floppy Days produced and contributed by my good friend Mike Whalen and it includes sound bites from many of the attendees of this year’s annual week-long KansasFest Apple II event that always happens in Kansas City, Missouri.  Mike is a long-time Apple II and retro-computer fan and one of the hosts of the currently-dormant Electric Dreams BBS Podcast.  I met Mike at the one-and-only KansasFest event that I’ve been able to attend thus far, that being in 2014.  I would certainly recommend the event to anyone that enjoys getting together with a large number of vintage computer nuts for an entire week, living the college dorm life, and generally immersing themselves in the out-of-date-but-still-loads-of-fun Apple II computer.  It’s one of things that you must experience at least once, although for most people it tends to be like Lay’s Potato Chips: no one can stop at just one.

I’m amazed at the effort and quality Mike put into this podcast.  I want to thank him and the Apple II KFest community for allowing me to air this ode to KFest on Floppy Days.

Enjoy!

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.

This a special interview show to help get the word out about an upcoming event: Vintage Computer Festival Midwest.  This will be the eleventh iteration of this event and I talk with Jason Timmons, one of the main organizers of the event.  He tells us all about the event, including guest speakers that will be there, exhibits, vendors and much more.  If you can make it to the Chicago area the weekend of September 10 & 11, 2016, I highly recommend that you drop in and enjoy the show.

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.

Welcome to episode 60 of the Floppy Days Podcast, where vintage in the term vintage computers simply means “cool”.  My name is Randy Kindig.  I am happy to bring you this month the follow-up or second of two episodes on the HP41C programmable calculator.  Once again, I have two stellar members of the HP41 community, Richard J. Nelson and Gene Wright, with me to bring you all the information you care to know about the HP41.  That includes a wrap-up to the history of the machine, tech specs, books, software, newsletters, modern upgrades, emulation, current Web sites, and so much more.  Before that, I do want to discuss a few new acquisitions that have come my way, as well as some feedback I’ve received from listeners.

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.

Ralph Rees, Editor, VAST TI-99 Newsletter

Hi, everyone and welcome to episode 58 of the Floppy Days Podcast.  I’m Randy Kindig.  To sort of finish off the TI-99 series of episodes I’ve been running, I have an interview-only show for you this month.  This interview is with Ralph Rees, president and newsletter editor of the VAlley of the Sun TI-99ers (VAST) back in the 1990’s.  He produced his high quality newsletter directly on a TI-99 system and received quite a few compliments about it while it was still being published.  Ralph still has an extensive TI-99 collection today.

This interview was conducted on June 7, 2015.
