Floppy Days 84 - The Sinclair ZX80 with Earl Evans

The Sinclair ZX-80 Hello and welcome to the Floppy Days Podcast for May, 2018, where we remind everyone of the days when everyone knew how to program a computer, not just use it for social media.  My name is Randy Kindig and I host this podcast. We are coming near the end of the computers to be covered on this podcast that were introduced at the beginning of the 8-bit era, when things really started to take off, that being the year 1980.  This month, we will be talking about a limited, inexpensive, but definitely historically significant line of computers known as the Sinclair Z80, ZX81, and Timex Sinclair 1000 and 1500. I was very happy to get an old friend, and vintage computer podcasting legend, Earl Evans to help me host this episode.  Earl does a great job of researching and discussing vintage computers and his help was great. In addition, I was able to get some members of the Sinclair ZX80/81 community to provide memories and to help provide information, as well as assisting with going through the topic of emulation.  As a result, there turned out to be so much information to present that it turned into 2 episodes. So, this month we will cover the history of the ZX80 computer line and tech specs and next month we will cover the remaining topics such as peripherals, software, emulation, magazine & newsletters, Web sites and more.  I’m also working on a special interview with someone key to the development of the ZX80 that I’m hoping will come to fruition.
