It looks like the adaptor I used to have for my Osborne 1.

Communication error!
While you where refering to the common (video game) switch boxes,
John did mention modulators! they are usualy the same size (ok,
the TI one is a true brick), but do what they are named, modulate
the composite signal onto a TV carrier.
The one I like most is the Amiga 520 (?).
