The reason to emulate it is that AmigaOS comes in different versions for AmigaOne and PegasosII which only have drivers for one machine and firmware so these only run on the specific machine. Adding this board allows another AmigaOS version to be used reusing already existing peagasos2 emulation. (The AmigaOne was the first of these boards so likely most widespread which then inspired Pegasos that was later replaced with PegasosII due to problems with Articia S, so these have a lot of similarity. Pegasos mainly ran MorphOS while the PegasosII version of AmigaOS was added later and therefore less common than the AmigaOne version.)
