Vintage 70s APF TV Fun Model 401A Video Game Console

Vintage 70s APF TV Fun Model 401A Video Game Console. Unit is in very good physical condition from outside view, the unit is powered by mains plug adapter or battery, and battery connection are is nice and clean. Turns on via adaptor and red power light turns on, also plays some kind of tune that reminds me of the old Pong game by Atari from my 80s childhood. All the switches move well, nothing visible is loose. I don't have a compatible TV to test it with in full, so selling as seen and part tested, no guarantee of working condition, but looks nice.
