Description

The Sinclair ZX80 and ZX81 Welcome to the Floppy Days Podcast with myself, Randy Kindig, and a whole host of vintage computers surrounding me, each one wanting their time in the limelight. This will be part 2 of the 2-part series on the Sinclair ZX80 & 81 computer line. Once again, I will have one of the grand-daddy's of vintage computer podcasting, Earl Evans, co-hosting with me as we complete the journey through one of the historically significant computers from across the pond. We will be covering the normal topics from where we left off the last show, so we'll be talking about peripherals, software, books & magazines, ads, emulators, Web sites and whatever else comes to mind. Before we do that, though, I do want to talk a bit about my new acquisitions and projects, let you know about upcoming shows so you can make your plans, and I might even have a little feedback. I want to thank Ian Bucknell for providing his thoughts and memories of the ZX81.
