Has anyone ever seen one in person? This ad was in the February 1987 issue of Keyboard Magazine. Even the M-DIT shows nothing, although Atari had a cartridge for dial-up based games before The Sega Channel, and the company that came up with this transmission method formed into America Online.

If this was published in April, I can see it being an April Fools Day joke as Keyboard has published in the future. But this??? It's more elusive than the ConnBrio or Movement Drum Computer.

Edit: This was Feb of 1986
