              Episode 23 -  Tandy vs IBM


              Description

              In this episode the Trash Talkers welcome vintage computing podcast pioneer David Greelish as a guest host.  Pete, Ian and David discuss how Tandy reacted to the the introduction of the IBM Personal Computer in 1981.  Tandy Radio Shack had all the advantages with its massive distribution network, its existing business focused Model II computer and with the forthcoming powerful Tandy 2000 computer.  How the company attempted to compete with IBM and eventually failed is the main focus of the discussion.
