The ZA-100-1 source listings (2 volumes) are for ROM version 2.5.

The other has no version number that I can see.  

The shipping cost is low either way - I use media rate so no big deal. 
 I do have one person interested so I would propose that if you think 
that is worthwhile to capture the listings (i.e. not available in any 
other place) then I will send them to you. You can break them apart, 
scan them and then pop them back in the box and (I will provide the 
return mailing fee's) either return them to me or send them on to the 
other interested party.  My contribution to the hobby. Suggestions?
