HP 9000/20 needs software

Title pretty much says it all. Over the long weekend (where did it go?) I finally got time to check out and power up the HP 9000/20 (aka: 9000/520) that recently joined the collection. It woke up without incident (tho there is still something rattling around in the monitor that I have not been able to find yet), but now needs something to run. You can only look at the "Looking for System" prompt for so long... So... (since I know there are at least one or two of these things in this group) What runs on this critter? And can someone provide copies of some disks? Diagnostics perhaps? Or dare I think it... Docs??? B^} I already suspect that I'm going to have to find a hard drive to go along with the unit to make it really happy, yes? Obvious by now that I've never worked with this particular unit before?
