Title: Robert Kiligus – The Start of the Color Computer
Robert worked with Tandy/Radio Shack on creating some software for the Model 1. Then he was approach on creating some software for the Color Computer that Radio Shack was working on. They set him up with a Motorola EXORterm with a 6809 board so he could develop and write the first 4 game/programs prior to the release of the Color Computer.
