Floppy Days 160 - The KayPro, Part 4, with Matt Jones Patreon: https://www.patreon.com/FloppyDays Sponsors: 8-Bit Classics Arcade Shopper FutureVision Research Tuc's Workbench YouTube Channel: https://www.YouTube.com/@floppydayspodcast Hello, and welcome to episode 160 of the Floppy Days Podcast for February, 2026. I'm Randy Kindig, your host. We are currently covering computers introduced in the year 1982 and, to that end, we are at the tail end of a series of podcasts about the Kaypro line of computers. Kaypro had a rich and varied family of computers; certainly much more so than I ever realized. I was able to interview David Kay, son of the founder of KayPro, and president of the company for some time, in the first two episodes. Last month, Matthew Jones, an aficionado of the KayPro computers and owner of many of the models, helped me talk about KayPro history, tech specs, and more, through the topic of using the machine. This month Matt and I complete the KayPro series by starting with books and magazines and ending with current Web sites and a lot more content in between. I will have a video version of this episode posted to the Floppy Days Podcast channel on YouTube (https://www.YouTube.com/@floppydayspodcast ) that will be available for everyone soon (after the early access period for Patreon supporters has expired). So, please consider becoming a subscriber on YouTube. Doing so helps support the podcast. You will hear ads from some great vintage computer stores, themselves vintage computer fans, throughout the early part of this podcast. For all of these storefronts, when you place an order, please mention Floppy Days in the notes or comments of the order. Doing so will help support the podcast. Many thanks!!

FLOPPY DAYS 158 - Interview with David Kay, KayPro - Part 2 Patreon: https://www.patreon.com/FloppyDays Sponsors: 8-Bit Classics Arcade Shopper and https://thekeep.net FutureVision Research Tuc's Workbench Hello, and welcome to episode 158 of the Floppy Days Podcast for December, 2025. I'm Randy Kindig, your host. We are currently covering computers introduced in the year 1982 and, to that end, this month I'm beginning a series of podcasts about the Kaypro line of computers. Kaypro had a rich and varied family of computers; certainly much more so than I ever realized. In researching Kaypro, I discovered that while Andrew Kay, the founder of the computer company, was no longer around, it turns out his son David, who ran the company for some time, was still around. I was able to contact David and he graciously agreed to talk with us for the podcast. Kaypro has a very interesting storyline and I hope you enjoy this. We talked so long that I decided to break the interview into 2 parts, so you'll hear part 2 this month, and part 1 was last month. Following that, we'll delve into episodes covering history, tech specs, etc. on the Kaypro. All the usual topics. It looks as though I'll have 2 episodes covering those topics. I will have a video for this posted to the Floppy Days Podcast on YouTube. One note here. This is one of the last videos where I used a videoconferencing tool that just didn't do a great job. It has a tendency to not keep up with video and you may note that the mouth doesn't stay in sync with the audio sometimes during the interview. In addition, audio-wise, you may hear some low clicks throughout the interview. I've since switched to Zoom and it seems to do a better job of audio and video quality, albeit more expensive. In the meantime, friend of the show Brian Cox offered to improve the audio quality using some high-end tools he had, and thanks to him, you benefit from his work. Hopefully, the clicks are gone and the sound from both David Kay and myself is better for the interview section. Thanks, Brian!

Floppy Days 156 - Interview with Paul Schindler, Computer Chronicles Patreon: https://www.patreon.com/FloppyDays Sponsors: 8-Bit Classics Arcade Shopper and https://thekeep.net FutureVision Research Tuc's Workbench Hello, and welcome to episode 156 of the Floppy Days Podcast for October, 2025. I'm Randy Kindig, your host for this "retro"spective covering vintage computers of the late 70's through the 80's and the people who were on the forefront of that incredible revolution. This month, I'm bringing you another interview episode with a tech media personality that was involved with the Computer Chronicles TV show (among many other things): Mr. Paul Schindler. Paul has a big personality and has a lot of great stories about Computer Chronicles and about the tech industry in general in those days. I really enjoyed talking with Paul and he made me laugh a lot! As you know, if you're a regular listener, I was able to interview Stewart Cheifet some ago about Computer Chronicles. Computer Chronicles was a great way to get information about computers in those early days and I've always wanted to do some follow-up. Thanks to S.M. Oliva, who is mentioned in the resulting interview, and who runs a blog called "Computer Chronicles Revisited", I was able to get in contact with Paul. Next up for Floppy Days will be a series of podcasts on the KayPro line of computers, for which I was able to line up an interview with a key figure from that company and was also able to find someone who knows a lot about the computer line to help me discuss the technical topics. Stay tuned for that series. As usual, I will begin this podcast going through new acquisitions and what I've been up to, upcoming vintage computer shows and more.

Interview with Karl Hornell - C64 Game Developer, Cartoonist, Author Patreon: https://www.patreon.com/FloppyDays Sponsors: 8-Bit Classics Arcade Shopper FutureVision Research Hello, and welcome to episode 155 of the Floppy Days Podcast for September, 2025! I'm Randy Kindig, your host for this podcast, where we talk about the computers that got many of us started in our careers and which still hold a lot of interest for us today. This month, I'm bringing you another interesting interview with someone who at an early age started developing commercial-grade software for the Commodore 64, which started him on an amazing trajectory with his career in software development, cartoonist, and more. His latest efforts include branching out into writing science fiction, which we will also discuss today. The person I'm referring to is Karl Hornell (Her-NELL). It's also an interesting story around how this interview opportunity came to me. I'm not used to getting contacted by an ad agency. This one indicated that their client, Karl, had just recently published a book and was looking for ways to advertise the book. They suggested that Floppy Days would be a great fit based on Karl's background and could be beneficial for both. I was skeptical at first, as I always am when I receive unsolicited, possibly spam email. However, once I researched Karl's background it became clear that he was an accomplished Swedish developer for the C64 back in the day, with some notariety. I felt his background might indeed be of interest to you, the listeners, and so happily agreed to interviewing Karl for the podcast. I hope you enjoy Karl's story and will consider taking a look at his new book.

Interview with James Nagle, Reboot of Compute's Gazette Magazine Patreon: https://www.patreon.com/FloppyDays Sponsors: 8-Bit Classics Arcade Shopper FutureVision Research Hello, and welcome to episode 151 of the Floppy Days Podcast for May, 2025. My name is Randy Kindig and I'm the host for this ode to computers that only survive in our memories and our collections. This month, I'm continuing to step aside from the ongoing series of episodes about the HP 97/67 programmable calculators to bring you a timely interview that basically constitutes current news. I don't often do this, but this news was so exciting to me that I wanted to bring this to all my listeners as soon as possible. The interviewee is James Nagle and the topic is the sudden and welcome news that James is planning to revive the iconic Compute! magazine under the equally-iconic name Compute's Gazette. I hope you'll stick around to hear about James' plans and are as excited as I am to find out where this goes. For upcoming shows, we do have one more episode in the series on the HP97 with HP calculator historian Wlodek Mier-Jedrzejowicz ("Vwahdek Meer-Yeng SHAY of itch"). I will air that episode very soon.

HP-97 Programmable Calculator History and Memories with Wlodek Mier-Jedrzejowicz and Everett Kaser Patreon: https://www.patreon.com/FloppyDays Sponsors: 8-Bit Classics Arcade Shopper FutureVision Research Hello, and welcome to episode 148 of the Floppy Days Podcast for February, 2025, where computers of the late 70's through the 80's are the Apple of our eye! (If you got that pun, then you're in the right place 🙂) First off, I wanted to mention that this month is the 12th anniversary of the publication of the very first episode of Floppy Days way back in 2013. That's right: 12 YEARS! A very small percentage of podcasts ever reach that sort of longevity. I can only think of one other podcast that's in my sphere of listening that has been regularly produced for that long or longer (Retro MacCast). I should be so lucky to produce a podcast as long as the 18 years that James and John have done. There are several reasons I keep doing this. I love talking about old computers, I love being able to interview incredible people that were actively part of the microcomputer revolution, I love feedback from listeners, and it keeps me out of trouble now that I'm retired from the daily grind of the workforce. This podcast wouldn't still be going if you weren't listening. The listenership actually has been pretty stable for the past several years, and I'm humbled and honored that so many continue to listen and provide feedback. Thanks to you and your support, what do you say let's keep this thing going till you and I both are tired of it?! 🙂 Okay, now onto details about this particular episode. I've been very focused recently on producing interviews with some amazing guests. Frankly, this will always remain an important part of this podcast, as the individuals who were the main drivers in microcomputers will unfortunately only be around for an increasingly shorter period of time. However, the main focus is, and always will be, covering the vast array of unique machines that existed in the late 70's through the 80's. I will admit that the amount of research and work to publish the microcomputer-specific shows is a lot; considerably more than the interview episodes. However, as I said, covering vintage computers and programmable calculators is the main impetus for this podcast. It has been a full year since we covered a vintage machine, so it's time to remedy that. To that end, in this episode we will be covering a vintage machine: the HP-97 and 67 programmable calculator. I speak of them as one, because, as we will cover in great detail, they are internally the same machine, with the main difference being the built-in printer for the HP-97. I was very fortunate to get a fantastic co-host for this episode: HP calculator historian Wlodek Mier-Jedrzejowicz ("Vwahdek Meer-Yeng SHAY of itch") . Wlodek has a tremendous amount of knowledge and experience with the HP calculators and I think you'll find his stories and background extremely interesting and helpful as we go through the history of the HP-97/67. In this episode, we'll be spending a few minutes to get to know Wlodek, then together we will cover the history of the 97/67. As another bonus, I also was able to catch up with another gentleman who has a lot of history with HP: Everett Kaser. Long-time listeners will recall that Everett worked for HP for many years on several of their calculators and desktop computers and helped with co-hosting the Floppy Days series of episodes on the HP Series 80. It turns out that Everett had spent some time at HP repairing the HP97 and he shares his memories of those times. Based on the amount of material that was generated about this calculator, it looks as though we're going to have 3 episodes on the 97/67, with the first being this one on history and memories, the second covering tech specs and several other topics, and a third episode to finish off coverage. I should mention that the HP97 episodes do veer from the timeline a bit. Whereas I've been covering the machines that were introduced in 1982 (with the last being the Grundy NewBrain), the HP-97/67 were introduced in 1976. By rights, the HP97 should have been covered in a very early episode, just after the MITS Altair 8800 and in the same general time frame as the Apple I. However, I felt it was important to go back and pick up this machine, so I hope you will forgive me for departing from the timeline order for this.

Interview with Dan Bricklin, VisiCalc Patreon: https://www.patreon.com/FloppyDays Sponsors: 8-Bit Classics Arcade Shopper FutureVision Research Hello, and welcome to episode 146 of the Floppy Days Podcast, for December, 2024. I am Randy Kindig, your host for this podcast. This month I'm staying with the recent interview theme, as I continue to get the opportunity for interviews with some amazing icons from the early personal computer days. This month, that person is Dan Bricklin, co-developer of the iconic VisiCalc software that helped kickstart the sales of early personal computers like the Apple II and began the important spreadsheet software category that persists until today. I published an interview with Dan's partner in VisiCalc (and in Software Arts), Bob Frankston, back in 2023, and now Dan adds to the story in his own words. Please note that I do plan to get back into producing episodes covering specific vintage computers. I've just had an amazing run of interview opportunities in recent months, which has reduced the time I had to do the research on computers for the podcast. Coming up in 2025 will be coverage of machines like the HP97, the Lobo Max-80, the Dragon, and the C64.

Episode 145 - Interview with Paul Terrell, The Byte Shop - Part 4 Patreon: https://www.patreon.com/FloppyDays Sponsors: 8-Bit Classics Arcade Shopper FutureVision Research Hello, and welcome to episode 145 of the Floppy Days Podcast, for November, 2024. I am Randy Kindig, your host for this audio tribute to the amazing variety of home computers that existed in the late 70's thru the 80's, before the influence of Big Blue changed the landscape forever. This month I'm continuing the series of interviews I've been doing recently with Paul Terrell. As we have discussed, Paul Terrell is a name well-known in the annals of computer history; probably most famously for his kickstart of Apple Computer through the purchase of one of Steve Jobs' and Steve Wozniak's first batches of Apple I computers for his Byte Shop. The Byte Shop was a very early computer store that was one of the few that existed in the world, at the time. In this interview, we continue to focus primarily on The Byte Shop, how it got started, what it was like, and much more. This is part 4 of a 4-part series on just that topic with Paul. If you want to know what it was like to run a computer store in those early days, this is the interview for you! Along the way, you'll learn even more about just what the home and hobby computer scene was like in those days. In future episodes, Paul and I will discuss other topics around his long and distinguished career, such as the aforementioned dealings with the fledgling Apple Computer, and other ventures in which Paul was involved after the Byte Shop, including a business that rented software.

Episode 144 - Interview with Don French and Steve Leininger, Co-Designers of the TRS-80 Model I Patreon: https://www.patreon.com/FloppyDays Sponsors: 8-Bit Classics Arcade Shopper FutureVision Research Hello, and welcome to episode 144 of the Floppy Days Podcast, for October, 2024. I am Randy Kindig, your host for this audio ode to the home computers of the past. This month I have a special treat for you. At the recent Tandy Assembly, which I will talk about in more detail later in the podcast, not only were there a lot of great people, exhibits, vendors, and camaraderie, but we were also blessed with having Steve Leininger as one of the guest speakers along with his partner in the development of the TRS-80 Model I, Don French! I recently had an interview with Steve Leininger (episode 142: https://floppydays.libsyn.com/floppy-days-142-interview-with-steve-leininger-designer-of-the-trs-80-model-i ), thanks to his willingness to be interviewed at the recent VCF Southeast in Atlanta. That was a milestone for my podcast, as I had always wanted to talk with Steve. I also had interviewed Don French several years ago, prior to his attending Tandy Assembly in 2017, in episode 53 (https://floppydays.libsyn.com/floppy-days-53-interview-with-don-french-co-designer-of-the-trs-80-model-i ). This time, however, I was able to get an interview with Don and Steve together in the same interview! That in itself was amazing and I think you'll really enjoy the back-and-forth between the two gentlemen who are obviously and correctly proud of the work they did to bring the TRS-80 to the world and Tandy into the computer business. Next month, I will talk about another computer rescue that came my way recently, and which is also tied into Tandy Assembly and Radio Shack computers. I'll not go into any further detail here as I don't want to spoil the story for you next month. But believe me, it will be fun both to tell and to listen to.
