My mother possesed one of these and always told me how much time she would sink into this product. It's nice to read more about it, as she sadly lost hers.

Incidentally, support for it is getting merged into MAME soon: https://mastodon.sdf.org/@philbennett3d/111258054181543746

Wife was 13 that holiday season, and was a fan of the pop star they used and doesn't recall ever even seeing one of those. Kind of interesting; she would have been the target market too.
