Agfacolor 80s which processing chemistry?

I purchased 2 rolls of Agfacolor 80s on ebay which have been expired since 1983.

I am curious whether this film needs to be processed in Kodak’s C-41/Agfa’s AP70 or in the Agfacolor process known as AP41.

According some research Agfa switched pretty late to C41, but I never found an explicit date when they did.

So I am unsure whether I can process it in C41 or if I have to process it in B&W chemistry, because AP41 isn’t available anymore.
