I purchased a Thinkpad 560Z and 560X at a carboot sale several months ago.
They weren't working and were both sold to me a for £20. I managed to get them both working and ended up stripping missing bits for the Z out of the X.
I now have a fully working 560Z and a load of backup components from the 560X.
Here it is running Puppy Linux 4.1.1. This OS is great for hardware like this and works pretty much out-of-the-box.
