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

I plan to buy some expansions for my MP-7, probably the 
Ensoniq Project to start. How am I supposed to install them? I 
don't see any documentation in the manual or the website. 
Should I just get out the screwdrivers and start pulling it apart? Is 
it in the manual and I'm just missing it? Also, what ROMS are 
favorites of you folks? I do mostly hip-hop and ambient D&B.
