It Just arrived in the mail...
As far as I can tell, this was the only home video game system ever released in the Soviet Union. There were arcade games, and there were multiple home computers that could play games, but no actual home consoles other than this. There was a Russian Famicom clone released in the early 90's called the Dendy, but this was after the collapse of the Soviet Union.
On the back it says it was built in 1980. It looks like a standard pong clone with detachable controllers, and it appears to play a couple different pong variations. I have no idea if the unit works or how I'm going to get video out of it, but I'll post any advances I make here. My plan is to crack it open and hook the composite video feed to the "synch on green" input of my NEC Multisync II monitor.
