HP 9000 Model 550 sold on eBay

I was wondering if this item would attract much attention. http://www.ebay.com/itm/262642624725 Sold for $787 this evening. I don't know anything about these systems. Looks interesting, but this bit of text didn't sound too encouraging: "The 550s have not held up particularly well over time. As of 2013, the museum had two units. Both units have non-functioning power supplies. The system control boards are also subject to damage from battery corrosion." http://www.hpmuseum.net/display_item.php?hw=581 Also this bit of text about the HP-UX 5.0 Operating System: "The downloadable file is an image of the system software tape for HP-UX on 500 Series computers. It was made from a 150ft tape. We obtained 47 read errors while imaging the tape, so it's probably not entirely intact, and we don't have a working 500 Series machine to check. However, the file contents of the tape are readable by issuing the BASIC CAT command from a 300 Series computer." http://hpmuseum.net/display_item.php?sw=534 Just curious if anyone knows much about these systems and if anyone has one in working condition. What might the chances be for whoever bought this system to get it into any sort of working setup? Does anyone else have software for these squirreled away in their collections?
