The design was eventually used as the basis for most MIPS-based Windows NT systems.
However, around 1990, the existing MIPS-based systems (such as the TURBOchannel-equipped DECstation or the SGI Indigo) varied drastically from standard Intel personal computers such as the IBM AT—for example, neither used the ISA bus so common in Intel 386-class machines.
For those and other reasons, Microsoft decided to design their own MIPS-based hardware platform on which to develop NT, which resulted in the Jazz architecture.
[1] Other operating systems were also ported to various Jazz implementations, such as RISC/os to the MIPS Magnum.
A list of systems which more or less were based on Jazz includes: There were also some MIPS systems designed to run Windows NT and comply with the ARC standard, but nevertheless were not based on the Jazz platform:
