Download NetBSD 5.1

NetBSD is a Unix-like operating system that originated in the 386BSD 0.1 branch. The first version, NetBSD 0.8, was released on April 21, 1993 and has been evolving ever since. Of the well-known BSD variants FreeBSD, OpenBSD and NetBSD, the latter can be run on most platforms. The developers released version 5.1 of NetBSD quite a while ago and the accompanying announcement looks like this:

NetBSD 5.1 is dedicated to the memory of Martti Kuparinen, who was the victim of a traffic accident in June 2010.

Martti’s technical contributions are too many to list here in full. He created and maintained numerous packages in pkgsrc, updated two packet filter solutions distributed with NetBSD and improved several hardware drivers. Beyond that, he was always helpful and friendly. His example encouraged users to contribute to the project and share their work with the community. Some of these users later became NetBSD developers themselves thanks to Martti’s efforts.
