In 1989, one year before the Super Famicom was released in Japan, the R&D4 department was spun-off and made its own division named "Nintendo Entertainment Analysis & Development" (commonly abbreviated as "Nintendo EAD"). The division was comprised into two departments: the "Software Development Department", which focused on video game development and was led by Miyamoto, and the Technology Development Department, which focused on programming and developing tools and was led by Takao Sawano. The technology department was born out of several R&D2 engineers that were assisting SRD with software libraries. After that, the same department later collaborated with Argonaut Games to develop the Super FX chip technology for the SNES, first used in "Star Fox" in 1993. This venture allowed the Technology Development Department to become more prominent in the 3D era, where they programmed several of Nintendo EAD's 3D games with SRD.
