This is a Nintendo Block Kuzushi (PONG, model CTG-BK6) console system from the Nintendo TV-Game series, a boxed set including the console and PSU.
The console has been tested and is in working condition, as shown in the photos, though some parts of the plastic shell have melted. The PSU (power supply unit / AC adapter) is a genuine Nintendo official product and has been tested. The box has a lot of damage, with some corners completely broken.
