a second prototype was created, utilizing a Macintosh IIsi case with the now-completed Motorola 88100 chip. Jaguar wasn't initially intended to be a high-volume mainstream system. Instead, mass-market RISC systems would follow sometime later. After Gassée left Apple in early 1990, the goal of the Jaguar project was refocused to be a mainstream Macintosh system instead of a new platform. The Jaguar project was folded into the Macintosh team in early 1991. While the Jaguar project itself never came to fruition, and Taligent never resulted in a functional operating system, many of the elements originally developed by the Jaguar hardware and software teams were brought to market in mid-1993 with the Centris 660AV and Quadra 840AV, including the Apple Adjustable Keyboard, Apple AudioVision 14 Display, GeoPort, and PlainTalk. The new case designs introduced with the Centris 610 and Quadra 800 had also originated in the Jaguar team. Development and partnership with IBM (1991–1993) By mid-1991, there was internal concern at Apple that the 88100 may not be the correct processor to move forward with as no other computer manufacturers had committed to using the processor. Using IBM's POWER was again considered, but it was a seven-chip design at the time, which was not desirable from a cost perspective. Engineers from Apple and IBM's Advanced Workstations and Systems Division met in Austin, Texas to discuss creating a single-chip version of IBM's POWER1 RISC architecture. Motorola was also present at Apple's request. IBM had already been working on such a chip, called the RISC Single Chip (RSC), in an effort to reduce production cost of their entry-level RS/6000 workstation systems. In these meetings, a number of changes were proposed to RSC that would facilitate lower costs, lower power usage, and higher yield production suitable for both the Macintosh and future RS/6000 products. In early July, executives at the three companies reached an agreement which was formally announced to the public in October. In addition to the new RISC architecture, which was given the name PowerPC, this "AIM alliance" had several goals, including creating an operating system based on Pink, an object-oriented scripting language called ScriptX, and a cross-platform media player called the Kaleida Media Player. Of the alliance, John Sculley said, "The Macintosh strategy paid off very well for us in the 1980s, but we didn't think we could establish the next generation of computing by using that model in the 1990s.
