The first generation of workstations from SGI were based on MC680x0 Multibus CPU boards, third-party IO controllers, and SGI's Geometry Engine based graphics subsystem, which could be up to a half-dozen boards.
The model 3120 the RCS has (rebadged by CDC as a Cyber 910) has a 68020 CPU, and a graphics system with 12 Geometry Engine chips.
