So, like i said I don’t think it’ll be compatible with a modern motherboard. I don’t believe motherboard manufacturers still add old port compatibility from something that old. So you’l need an adapter to act as an interface to use it on a newer system as the current ones wouldn’t be compatible. Or you can do as Norway said and bring it to a computer shop, they should be able to help you out.
I did have a look just to confirm the hard-drive type, so I can tell you definitely what cable you’d need but I couldn’t find details on the models of these computers online.
