MM> Which architecture was that?

680x0 -> PPC (Mostly developers would just write FAT code, IE applications would contain code for both the legacy arhitecture and PPC.

PPC -> Intel.  PowerPC and to some extent legacy code ran in Rosetta, which was a dynamic translator to execute code on the fly during the transition.

Intel -> Apple Silicone.  Similar methods were used when Apple went from Intel to their own chips, called Rosetta II I believe.

Microsoft uses a similar method on the ARM64 version of Windows to run legacy X64 code (In my oppinion, they do a slightly better job than Apple when running legacy apps.  The only problem I run into when using Win11 ARM64 in a VM on an Apple Silicone box is with legacy realmode drivers.).
