I got a IPX in 2022 and restored it. I was a bit lucky and mine was an ex-IBM unit that came with the Weitek SPARC POWER μP processor (80 MHz) upgrade.
It makes for a pretty good project box as one of the smaller SPARC machines. Lots of documentation from hobbyists, Sun's own service manuals, and OpenBSD/NetBSD. Flash SCSI disk replacements are much easier to get your hands on now (I used a ZuluSCSI).
I've kept a log with photos: https://drislock.org/pkb/machines/perfect.html#a-little-lunc...
It seems to have been part of IBM's IBM-IPT Tester system. Hostnames were interesting: flower, owl, piglet, diamond, hotlips. I didn't get any interesting data though since this system relied on network resources.
