This accessory was introduced in 1977, together with the Color TV-Game 6 and Color TV-Game 15.
|The CTGA-901R powered the Color TV-Game series|
Both Color TV-Game 6 and Color TV-Game 15 could also be powered by batteries. Color TV-Game Racing 112 and Color TV-Game Block Kuzushi, on the other hand, only worked with the CTGA-901R AC-Adapter.
|Notice in Block Kuzushi box regarding compatibility of the CTGA-901R adapter|
The adapter was not included with any of consoles in the Color TV-Game series, and had to be bought separately for ¥1,500. This helped keep the price of the console (seemingly) down, but also prevented unnecessary duplication of adapters for people who bought multiple games from the Color TV-Game series. The fact that the adapter was compatible with the other games was clearly communicated in manuals and on the boxes.
The adapter provides 9 volt DC.
|Two versions of the CTGA-901R adapter exist|
Two versions of the CTGA-901R exist, identical in price and specifications, but different in size.
|The two versions of the CTGA-901R adapter side by side|
The smaller version is the older of the two. The larger version is more common to find these days.
