Emax

Greetings to the list members.
First post on the list, i wanted to ask about the similarities between the 
original Emulator I and EII libraries and later Emax libraries, did many 
banks get moved from the early emulators to the later Emax machines? Was 
there a lot of overlap in the libraries?
Also id like to know if you guys have seen the Zip disk packages on Ebay, 5 
zips for Emax 1 and 2 zips for Emax II, supposedly with the complete factory 
libraries for each machine spread over the zip disks, has anyone bought from 
them?
As for me, i bought an Emax 1 rack fairly recently and am hoping to add an 
internal scsi zip drive in the future, i used to have a few vintage 
samplers, but now the emax is the only machine i have.
Cheers, Rob.
