Recently, hinted by people on Discord, Neozeed found a Win64 compiler for AXP64 / ALPHA64, that came in as part of Platform SDK from 1999. This was to let Windows developers test compile their programs to make sure they are “64bit ready”, before the hardware was even available. However, as this was a cross-compiler from IA32 to IA64 and AXP32 to AXP64, there was no actual way of running any of the binaries. Until Itanium finally came out, after long delays. Sadly, 64-bit Alpha AXP Windows was never released outside of Redmond.[…]
And that would be the end of the story… if not for one reader, who contacted Neozeed after his previous post, and shared a disk image… containing a 64bit version of Windows 2000 for Alpha AXP! The reader got it from a lot of random lot of hard disks bought from an e-waste, years ago, and completely forgot about it until they saw the blog post!
And you bet they got it up and running. This find is extraordinary.
