We just recieved our 330 and have a few questions. 1) Are memory's for the Sparcstation 330,370, SPARCserver 330, 370 and 390 interchangeable? Has anyone tried this? 2) Has anyone been able to expand SPARCstation 330 memory capacity over the stated 56 megabyte? 3) How is a 330 different from a SPARCserver 390.
