Basically, the Ultima I-VI Series CDs are just the two previous trilogy releases combined into one. They contain all the maps and manuals, only the software is on CD instead separate disks.
The much rarer Software Toolworks edition has a thicker but also shorter box - as a result, the folded maps and the First Trilogy manual had to be bent slightly to fit in.
