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.
