About NetBSD/alpha
NetBSD/alpha is a true 64-bit system that fully implements the LP64 architecture, using 64-bit pointers and 64-bit long integers (standard integers are still 32 bits) in a linear four terabyte (4TB) address space. NetBSD/alpha was the first free OS to run on the Alpha and supports by far the largest number of alpha system types of any free OS.
NetBSD runs on almost all of the existing alpha systems, including some of the more unusual ones with proprietary or legacy bus architectures, such as the large-scale 8400, all of the TURBOchannel systems, the 4100 series, and the EISA-only Jensen.
