The first implementation was the PPC620 from Somerset, eventually only used by Groupe Bull. The S70 and S7A use a chip from IBM Rochester also used in AS/400s. The Power3 (aka PPC630fp) is yet a third 64-bit PowerPC implementation. IBM's recent 64-bit PowerPC chips are augmented to support additional requirements of AS/400 systems.
