[24 May 2020] Coming soon: A trove of wiki content dated from 7 May 2012 has been discovered on the website.

The content will be gradually added to this wiki to restore it to its former glory. is a great free resource for internet users and is a very worthy cause for charitable donations for those who can afford to do so.

The server hosting this website has also been migrated to an x86_64 after the cloud provider discontinued the ARM aarch64 service, but is still using electricity from low carbon footprint sources.

What happened to the files previously on

You're (mostly) in luck! See Former content for how you can download your own copy of the non-wiki contents of the previous website, or whatever files you were looking for. Some or maybe all of the contents of the original wiki have been found on and are in the process of being restored to this site. The website was relaunched on a new platform (as of May 2015) and most web links from before then will now be broken. However, work is being done to reconstruct the content on this website.

Linux distributions and other operating systems for Alpha

There are many Linux distributions and other operating systems for the Alpha architecture, some of which are actively maintained and some no longer supported.

See the List of operating systems for Alpha.

Using Alpha today

SCSI hard disk emulator for retro computing

As Alpha is effectively retro computing, it joins many other older computers that require increasingly rare SCSI hard disks. The SCSI2SD card connects to a 50-pin SCSI bus and emulates a hard disk using storage on an SD memory card.

This has been tested by the author on a Compaq XP-1000 Professional Workstation. The SCSI2SD card is seen as a bootable device in the SRM, which enables it to be used to load the Debian Linux kernel. The kernel can then load the rest of the OS from any other device in the machine that it has a driver for, in this case an IDE disk attached to a Promise IDE controller in a PCI slot. By only using it to load the kernel this avoids questions on whether the SD card has sufficient performance for a regular filesystem.

Alpha History

The Alpha processor was developed by Digital Equipment Corporation (DEC). DEC was later bought by Compaq, which then merged with HP. Alpha always had a reputation for excellent performance and could run many different operating systems.
