Office suite
The MIPS Magnum R4000 was supported by Windows NT from version 3.1 (released in 1993) through version 4.0 (released in 1996). However, support by Microsoft for all MIPS systems ended after the release of Windows NT version 4.0, and useful software for Windows/MIPS — either from Microsoft or third-party vendors — was very scarce even when MIPS was supported (for example, Microsoft never ported its own Microsoft Office suite to MIPS).
