This is the Nintendo “Advanced Video System,” a Famicom-era concept for a home computer shown at CES in 1985. (Aw, look at the cassette drive!)
If you don’t see any wires at all, it’s because the entire prototype was designed to communicate via infrared. With all the hassles we have with modern radio-based wireless peripherals, I can only imagine trying to build a system around infrared would have been much more frustrating for designers and end-users both.
I really like the look of the AVS—and not just because it looks like a NES. The abundance of right angles broken up only by the 45° cursor keys looks modern still. (In perhaps a retro-modern way!)
