Ah... I can shed some light here. As a 12 year old boy in 1977 I received one of these as a birthday present. I can recall begging my mum to get it. It cost her $29.99, and in those days that was a lot of money to spend on a present. The game console was purchased assembled and bought from Myers toy department at the time. I can recall I could tune it to either VHS 0 or 1 at a flick of a switch. While the game was in in B$W it provided years of fun until I bought my first game colsole in 1983 (An Atari 2600).
