I did tests with my P2K and Orchestra modules (that one is Japanese  
design variation of Virtuoso). Here are results:

P2K:
- OS 2.26
- Composer card
- World card in slot 2

OS checksum 6C93D828

Test 14:
Slot 1 passed
Slot 2 passed
Slot 3 No ROM in Slot
Slot 4 No ROM in Slot

Test 17:
Slot 1 - 5b996906
Slot 2 - 1c1a027f
Slot 3 - -------------
Slot 4 - -------------

---------------------
Orchestra:
- OS 2.26
- Orchestra 1 in slot 1
- Orchestra 2 in slot 2

OS checksum 6C93D828

Test 14:
Slot 1 passed
Slot 2 passed
Slot 3 No ROM in Slot
Slot 4 No ROM in Slot

Test 17:
Slot 1 - 034a2be9
Slot 2 - a46d2a85
Slot 3 - -------------
Slot 4 - -------------

Sound ROMs differs in size, type (ROM or Flash ROM) and voltage - some  
were for 5 Volts, some for 3.3 Volts.
