Floppy Days 155 - 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.

The TRS-80 Model III and 4 On the personal computer timeline, we’re currently in the 1979 to 1980 time frame. I do apologize that this month’s topic, the TRS-80 Model III and 4, is being presented slightly out of order in that there were a couple of machines introduced a little prior to this that I plan to cover. However, as I already had this one recorded I decided to present it now rather than hold up publishing an episode just to maintain a precise order. As usual, I have a short preamble before we get into this month’s topic, covering new acquisitions, upcoming shows, and a little bit of feedback. I was lucky enough to get author and vintage computer collector Michael Nadeau to agree to co-host this episode with me, so this should be a fun and interesting episode.
