Interview with John Grant - Developer of the OS & BASIC for the Sinclair ZX80 In the last show Earl Evans and I covered part I of the Sinclair ZX80/81 line of home computers; its history and tech specs.  Before delving into part II, we’re going to have a topic-relevant interview this month. I was able to, with the help of Kevin Palser, track down and interview Mr. John Grant, a man whose name we mentioned several times last month when going through the Sinclair ZX80 history.  You see, John is literally the gentleman who wrote the operating system and BASIC for the ZX80. He still owns Nine Tiles today and still has the rights to that OS. I think you’ll enjoy this discussion with a true vintage computer pioneer.
