Suns have been my primary focuz for a few years now. From the hardware to the software to the way they were used, it's all very important to me, and I'm happy to be able to own some of these machines to do resarch and archival work for them. My primary focus is archiving and documenting all manner of resources for these machines.

Shinki was my first Sun machine, and it is what I've done the most with. I have Solaris 9 and OpenBSD installed on it. I replaced the timekeeper as well, which has been wonderful. Mima and Sadu I acquired at the same time. The former I have running Solaris 2.6 and the latter doesn't have anything installed on it presently and will need work before I can do much with it.
