I don't know. Okay, I know that's no help, but I thought you might feel a little better if you knew that at least one person read your question.

I can email you a copy of the Hardware Developer Notes for the ANS, if you think you might find your answer in there. However, I doubt it will mention it explicitly, if the answer is no. Most likely, it will only be mentioned if the answer is yes.

Oh, you might wish to join the Classic Computer email list. I think if you google on cctalk and cctech you'll turn it up. Cameron Kaiser, amongst others, is on that list and he's a very knowledgable ANS user.
