HP initially released the two modules separately
00041-15002 Statistics Pac (4K FOCAL module using plug-in-port lower page)
00041-15003 Mathematics Pac (4K FOCAL module using plug-in-port lower page)
then later on they re-released it as a combined module
00041-15049 Math/Stat Pac (4K FOCAL Math module using plug-in-port lower page and 4K FOCAL Stat module using plug-in-port upper page)
