One of the most interesting things I got at the convention this year is the BudJones set of parts for showing a customer the edge-spot pattern of a proposed chip. You snap together a piece A, piece B, and Piece C of the appropriate colors and you can see how the combination looks. This goes back to simpler days when the chip makers didn't offer the zillion combinations of edge marks you can get today, but you could see how up to two colors looked with a base color.

In the picture below, I've assembled white and green to match what was made for Sahara Tahoe in 1980. There are 50 different colors, numbered from 1-50. My set is missing 1-2-3-7-8-18-27-29 in case anyone should happen to have these in their miscellaneous boxes and not know what they are.

I had never had a chance to play with one of these sets and originally thought you could assemble a complete chip this way. Not so, unless I am missing a big chunk of additional components.

Thanks to Janice and Jerry O'Neal for parting with this very interesting piece of chip history!
