Palladio Developer

A few months ago a friend gave me a small quantity of Palladio paper including the instruction sheet/booklet. I realize this paper is at least old enough to vote now, but I'd like to try it. Apparently Palladio specified their own proprietary developer, of which I have none.
Can anyone suggest a readily available developer that would work with Palladio paper?
TIA,
Will

potassium oxalate

Interesting as that is what I already have on hand for "conventional" Pt/Pd development. Good deal!
And is a fixer required for Palladio? The booklet does not address it that I can see.

Thanks again!

Potassium Oxalate developer works well, followed by a standard clearing agent.

It was recommended to humidify the paper before exposure but I got excellent results without doing that.
