Question about Lenovo Mini-DisplayPort zu

I would like a Mini DisplayPort to HDMI output cable I'm not sure if it's for an old macbook... I know there were several plugs... we have 2 of these iBooks with two different outputs... do you have these models... they are about 10 years old and more so they were Thunderbolt 1 and 2 ports I think! one of each would be a good thing... if it really doesn't work I can send them back to you? what are the order numbers!
