Please take this with a grain of salt...
For several years at my current job I worked with a developer named Mark Thompson. One day a few of us we were schmoozing in the kitchen talking about classic video games, when I mentioned being an Intellivision collector. Mark's ears perked up, and he said, "Oh? Do you have Ladybug?". I said I did, and he replied, "I worked on that one." Now, to what extent I can't be sure, and unfortunately he passed several years ago, so I can't follow that lead.
