Connor VideoPhone (lost education console spinoff; 1986)

I like this one.  This is a featured article.

Very little information is available on the VideoPhone. On June 19, 2018, YouTube user Kevin McQueary uploaded a video taken from a camcorder pointed at a computer screen. An eBay listing for the "Connor VideoPhone" is shown on-screen. The listing itself is no longer viewable on eBay, and no other evidence of this console variant has resurfaced. The console appears to have the same four-button arrangement as the original VideoSmarts, and the box has the same image of a VCR and the Teachin' Teddy character as the original VideoSmarts packaging. It is unknown if this was just a different form factor for the original VideoSmarts console, or if this console had a different set of games which utilized the phone handset.

Its games has not resurfaced since.
