Hewlet Packard A4 Scanner (Aldwick PO21)

Hewlet Packard Scanjet 4400c A4 scanner. No cables or power supply. It's fairly old, belonged to my father & hasn't been used for a while, so I've no idea whether it still works. Comes with an installation disc for Windows XP, NT etc. I don't know whether it will work with later Windows versions. Will require a 12VDC power supply and connection cable.
