RS/6000

History

The first RS/6000 models use the IBM Standard Micro Channel (SMC) bus; later models use PCI. Some later models conform to the PReP and CHRP standard platforms, co-developed with Apple and Motorola, with Open Firmware (OpenFW/OFW). The plan was to enable the RS/6000 to run multiple operating systems such as Windows NT, NetWare, OS/2, Solaris, Taligent, AIX and Mac OS but in the end only IBM's Unix variant AIX was used and supported on RS/6000. Linux is widely used on CHRP based RS/6000s, but support was added after the RS/6000 name was changed to eServer pSeries in 2000.
