Shipping damage. No holders. Working units with holders going for $450 on ebay, like new or refurbished for top dollar, this one $150 tops.
Contact one of the ebay members offering service for the Coolscan 8000 about repair.
The plastic front can be fixed with epoxy. The switch board is likely broken. Due to the dent in the metal cover the frame may be bent.
I could get it to power on, fix the front plate, but cannot guarantee being able to get it to scan properly.
