I had this sound card in the pile of old scrap for some time, but never really tested it.
Under close inspection it appeared suspiciously scratched. I've touched it with IPA, and the label faded away.
Trying to identify what's actually was sold under the name of Yamaha I found images of cards that appear similarly sanded down and relabeled.
Any idea what's that really is? Or is it a sound chip at all?
I could imagine faking the cache chips on early motherboards, but this one looks too badly executed.
