Here is the bottom of a canadian coco-3, Thanks to Gordon Frost!

A double row of square pins was soldered to the bottom of the game slot connector. A 40-pin wide ribbon cable, is installed to connect external projects to this extra game slot. Notice the crack in the plastic due to over-zealous cutting!

The IdeZilla can be hooked to this connector if the second IdeZilla header is used.
