User guide for compaq contura 400C

Question

Hi there, I don't mean to take up too much of your time but I'm trying to help a freind find a manual for his compaq 400C. Your link suggested that we might be able to get one, or download one for free. If that is so that would be great. It's not my deal so I don't have a budget but if you could point me in the general direction I would be grateful. Thanks!!
