Randy Kindig and Earl Evans started covering the Sinclair ZX-80/81 in the last episode of FloppyDays podcast, mostly talking about its history and tech specifications. To continue the historical coverage of the early Sinclair machines, Randy was able to locate and interview John Grant, owner of Nine Tiles which was responsible for the operating system and the BASIC language shipped with the ZX-80.
If you haven’t heard of FloppyDays, it is a podcast about retro computers following the dawn of the mass-market microcomputers from the late 70s and throughout the 80s. I’ve been listening to it since it started, 5 years ago, and I can’t recommend a better multi-platform podcast. Now with 85 episodes, it is easy to say that FloppyDays played a key part in registering and promoting the retro computer history.
