Ran across this going through my old stuff. The pre-pre-pre-release docs for the SPARCstation-2 (Calvin). Was given to us lowly techs who were destined to debug them coming off the manufacturing line. When I started at Sun, I was a lowly failure analysis technician, the good jobs went to Stanford grads, DeVRY grads needed to come in through the back door. Eventually made my way into engineering and then SunLabs (where the real party was).

A cover page for a document called "Calvin" CPU board which was to become the SPARCstation 2. Names of the design and manufacturing engineers listed on the same page. Version humorously says 9.99+E+99
List of features to be found on the SPARCstation2 motherboard during pre-release. 40MHz clock and a whopping 64MBytes max on the board! Good times!
A couple of schematic pages from the SPARCstation2 while still under development. Legend says "P0" which was usually very early in the development status.
SPARCstation2 Hardware overview page showing some timing diagrams for the reset timing along with a block diagram of the main board.
