CD-i member Ekim Skirdneh: "I bought a few years back, this boxed CD-I 452. And always wondering why the 452 and not just 450 with a sticker on the box with “incl video module”. Now a saw the light 😉, I came across a Dutch Wehkamp catalogues page. This was printed in the summer of 1996. When you see a system name with 2 at the end, it’s has already a video cartridge in it. Does someone has a boxed 212, 472 or 222? I’m curious of they exist...."
