That would be the Drawing Number. The part number is one higher and is on one of the connectors. Listed here as a 8K memory board for AN/UYK-20( page 15) : UYK_20_20A_Technical_Summary_May91.pdf (trailing-edge.com) <http://bitsavers.trailing-edge.com/pdf/univac/military/an_uyk-20/UYK_20_20A_Technical_Summary_May91.pdf> I never saw one without the covers.
