Powerbook 5300cs by apple. It booted on the hdd drive before I smashed it to destroy data. I will provide the flex cable for the HDD. I think all this thing needs is power, an HDD, and an OS.Worked fine on line power.Battery is toast, and it left some corrosion. Upon internal inspection, corrosion is rather limited, having only damaged the battery contacts and not much else.The power brick is non-functional. The shell is broken from my attempts to fix the power brick. To power the laptop you'll need to supply 24V dc from the power brick's output.
