The earliest reference is on pages 15-16 of HPX Exchange (August/December 1988), where the verbatim content of my posting above first appeared. For the record, the 3 hidden HP-42S functions were discovered in a Jack in the Box fast-food eatery (23812 El Toro Rd, Lake Forest, California 92630) while eating a cheeseburger, on 9 November 1988. Museums always seek historical context, so there it is. Big Grin
