Hardware Revision Notes : The only difference between the Model3 step2.0 and step2.1 boards is that the architecture packaging for the custom IC's was moved from GullWing type to BGA's
Notes : With Model 3, Sega decided to design a new system from the ground up. Again, going with the company that they had formed a good relationship with, now named Lockheed Martin's Real3D division (Martin Marietta had now merged with Lockheed to form Lockheed Martin and Real3D was created from the combined 3D graphics resources of MM and Lockheed's own). They were brought in to assist in developing the brand new graphics subsystem, which ended up being the twin Real3D/Pro-1000 chipset, stunningly powerful for their time.
Emulators : MAME (Preliminary)
