Floppy Days Vintage Computing Podcast

• Floppy Days 156 - Interview with Paul Schindler, Computer Chronicles

  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.

• Floppy Days 155 - Interview with Karl Hornell, C64 Developer, cartoonist, author

  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.
