My research so far seems to indicate that using the generic ID 72 is OK.</div><div><br /></div><div>I\u2019ve seen mention of the OBP command real-machine-type and I will try that out and see if it returns anything. </div><div><br /></div><div>The machine itself seems to have a stock SS20 logic board in it. It uses 2 50-pin SCSI drives, which surprised me. They sit in the case like a Sparc2 on different sleds.</div><div><br /></div><div>It has two SuperSparc processors I\u2019ve not identified yet, ROM rev 2.22, and 144MB of RAM.</div><div><br /></div><div>I\u2019m looking forward to firing this guy up!
