Emu XL-7 & MP-7 User's Group

Hi,

I am a fairly new owner of a PK-7, which I'm primarily using as a sound module as I've only learned sequencing in software so far.

I frequently see various E-Mu Proteus line modules for sale on my local Craig's list.

Some of them sound interesting, but I'd like to have a resource to know which ones are compatible with Prodatum and which ones have ROMs that could be used in a Command Station.

Is there a general resource for this information? 

Thanks

DF
