The latest version I have is 5.1, and that uses ECOFF.

I don't have any specific examples, but I can well imagine people
keeping an Alpha machine for no other reason than the ability to run
some (old) application only available (to them) for OSF/1. Running them
on Linux rather than Tru64 brings the advantage of being a modern system
in other regards.

For anything open source, there's little reason to keep the Alpha at
all.
