Even you folks in the 1980's were down with the
DIY mods. Check out this badass cassette deck boom box with an integrated TV. It is pretty much straight out of Radio Shack, but hey, what gadgets in the 1980's weren't straight out of Radio Shack.
It may not seem that cool right now, but I'm sure the fool who had that in their dorm got all kinds of tail. Boom boxes are freaking awesome.

Update: Okay, I'm an idiot. It wasn't a mod, I'm just too young to remember. Still cool to reminisce, though.
