HP-IL to SCSI Adapter

I acquired one of these recently (HP P/N 5061-3166) and I'd like to know more about it. For which equipment was it intended? With what other non-intended equipment could it be used? I scanned the info sheet that came with it and posted it here (PDF:) http://chiclassiccomp.org/docs/content/computing/HP/5959-1451_E2_HP-IL_SCSI… It did not include the power adapter but at least I have a part number for it so finding a substitute shouldn't be too difficult. Seems to be the same one used with the 95LX, giving 9VAC. The sheet tells you to call the HP BBS (heh) and download SCSIDISK.EXE, which suggests that this was targeted to a DOS machine. HP 110 or the LX series of palmtops. Although on second reading, it seems as if that would only be to "perform SCSI diagnostics," so it's possible that this interface may also have worked with non-DOS HPs. Anyone have any clues to throw out?
