Does anyone know where I can get a list of ROMs with the AP-XXXXX-XX numbers and how they correlate to the sound collection/title?

I see the SIMM file in the collection, but I see a ROM on ebay with the number AP530-01 listed as an "Audity" ROM or "Xtreme" Rom. 

1) Is this the ROM from the Audity 2000? 
2) And if so, can I use it in my PX-7 and get full PX-7 functionality out of it? 
3) Does it have 32mb of sounds?

Thanks for any info in advance. 

Aloha,
