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.
