I might be wrong. The original Indigo (R3000-based) used a different chip set from the Indigo R4000, Indy, and Indigo2, which shared a common memory controller. The latter machines use vary a bit in the details of their peripheral chips, the parts are mostly either the same or different mainly in being later revisions in some of the systems. The Indigo2 added EISA bus support (along with GIO).
