Question

I'd like to run an old OSX version ( Leopard or Lion ) for compatibility with third party musical hardware which requires one of these OSX versions. I only want to do basic recording with a previous version of Studio One.

You would look at Amazon, Ebay and Audio Forums for people and companies selling it.

For example:
