High Quality Content by WIKIPEDIA articles! FX!32 is a software emulator program that allows x86 Win32 programs to execute on Alpha-based systems running Windows NT. Released in 1996, FX!32 was developed by Digital Equipment Corporation (DEC) to support their Alpha microprocessors. At the time, there was a belief that RISC-based microprocessors were likely to replace x86-based microprocessors, due to a more efficient and simplified implementation that could reach higher clock frequencies. The one thing that held Alpha back was application-compatibility with existing Win32 x86 applications.
