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!!
