Interview with Brian Bagnall, Author “Commodore, A Company on the Edge”

Welcome to the Floppy Days Podcast, where old computers survive to tell another tale.  My name is Randy Kindig.  In the previous couple of episodes, I covered the history of the Vic-20 computer with the help of Neil Harris, Brian Bagnall, and Michael Tomczyk.  Although I used some audio clips from each of those gentlemen to walk through the history timeline, I actually have a full-blown interview with each that I want to share with you over the span of three episodes.  I’ve already published the interview with Michael Tomczyk, leader of the Vic Commando Team and assistant to Jack Tramiel.  Next up, I am publishing the interview with Brian Bagnall, author of the book “Commodore, A Company on the Edge” and who is working on the follow-up book “Commodore: The Amiga Years”.

Before we get to that, I will very briefly cover upcoming shows and a bit of feedback, but then we will get right into the interview with Brian Bagnall.

Interview with Michael Tomczyk, Vic-20 Commando Team Leader at Commodore

Welcome to the Floppy Days Podcasts, where old computers are the best computers and new old computers are even better.  Last month, I covered the history of the Vic-20 computer with the help of Neil Harris, Brian Bagnall, and Michael Tomczyk.  Although I used some audio clips from each of those gentlemen to walk through the history timeline, I actually have a full-blown interview with each that I want to share with you over the span of three episodes.  For this episode, I will be publishing the interview with Michael Tomczyk.  Michael was with Commodore for some time, was an assistant to none other than Jack Tramiel, and was the leader of the team known as the Vic Commando Team.  He was happy to talk about his time at Commodore and turned out to be a very interesting interview and a great guy with which to talk.

Before we get to that, I do have a few housekeeping items to cover, such as a few new acquisitions, some brief news, and a bit of feedback.

The Commodore Vic-20 - History, with Brian Bagnall, Michael Tomczyk, and Neil Harris

Welcome to episode 69 of the Floppy Days Podcast, where our computers may be old, but that’s why we love them.

In the vintage computer timeline, we are in 1980.  The next computer I want to discuss that debuted that year is the Commodore Vic-20.  The Vic-20 is significant because it was the first color computer to sell for less than $300, at a time when other home computers with color graphics were 2 to 4 times that amount.  It also was the first home computer of any type to sell over 1 million units.

In this first episode about the Vic-20, I want to cover the history of this machine: why it was developed, some of the stories around its development, what happened after its release, and when it was canceled.  To that end, I contacted some notable persons that were involved with the roll-out and support of the Vic-20, as well as a person who was involved in documenting Commodore’s history.  The first person I contacted was Michael Tomczyk, who was an assistant to Jack Tramiel at Commodore and who led the so-called “Vic Commando Team”.  Michael was intimately involved in the marketing and support of the Vic.  In addition, a key member of his team, Neil Harris, agreed to help with this episode as well.  And, finally, I talked with Brian Bagnall, who you might recognize as the author of “Commodore: A Company on the Edge”.  This is an amazing line up of people who are very familiar with the Vic-20 and its history and I’m very lucky to have been able to get their assistance with telling its story.

Before we jump into that, I will cover a few new vintage computer items I’ve acquired, cover a bit of news, and cover a bit of feedback I’ve received.

Interview with Bill Kemper, HP Employee and HP Series 80 Software Engineer

Hello, again, and welcome to episode 68 of the Floppy Days Podcast.  This will be a fairly short, interview-only show.  As a final piece of the recent series of podcasts on the HP Series 80 family of machines, I was able to sit down and talk with Mr. William Kemper.  Bill worked directly on software for the HP Series 80 and later was the manager of software engineering for the line until it was canceled.  He then continued on for some time with HP until the merger with Compaq around 2002.  In the interview, we discuss Everett Kaser, who worked for Bill, and who was one of my co-hosts for the HP Series 80 podcasts.

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.

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 and Vassilis Prevelakis of  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.

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,  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.
