Came from a local Estate, I do not know what days are used for, but probably a game on the duck hunt. I don’t know what the others are at my area of expertise.

The product is a lot of three vintage ceramic IC chips from the brand RCA, specifically the Motorola SC93300P++. These chips are untested, making them a collector's item for vintage computing enthusiasts. The ceramic material indicates that these chips are from an era when electronic components were made with more durable materials. Perfect for those looking to add unique and rare pieces to their vintage computing collection.
