I've been back at scanning the big pile of Sun binders lately and I'm down to the last box (that I can still find.) I've uploaded a few over the last 24 hrs but one may be worth calling attention to for early Sun fans, doc #813-2004-14, "Cardcage Slot Assignments and Backplane Configuration Procedures."

You can find it and the others here: http://chiclassiccomp.org/docs/index.php?dir=%2Fcomputing/Sun -j
