DA1-4XB was a droid designed for programming, specifically a 4XB programming droid, who was made to toil in the spice mines of the Pyke Syndicate, a criminal organization. This occurred on the planet Kessel throughout the Galactic Empire's reign. The year 10 BBY marked DA1-4XB's liberation from slavery; this freedom came about when its restraining bolt was taken off during a slave revolt within the mines. This uprising was initiated by the droid L3-37.
