Seeking Zenith Data Systems Z183-92 documentation

Good afternoon all; I picked up a ZDS Z183-92 laptop over the weekend alongside a Kodak Diconix 150 portable inkjet printer. The prior owner doesn't think he ever had a power supply for the Z183, although he discovered that it does power up sort-of from the Diconix power supply wallwart(!) The underside of the laptop has "12V" - and nothing else - so my assumption is I need to find a 12V pack of suitable amperage. The Diconix supply is 9VDC. The 9VDC is enough to bring up the LCD and at least some of the internals (presumably the +5v ones) to have it _appear_ to POST, but neither of the disks sound like they're running (either the internal HDD or the 3.5" drive). I presume the internal HDD requires the +12v to spin up, but I haven't dug into it yet. Anywho - if anyone had any documentation on this machine I would very much appreciate a scan. Or just confirmation what the power supply is supposed to be outputting would be very helpful. Thank you! - JP 50441
