That's good news, Mike.

I have some AAC/N chips- they just type wrong keys on an Apple II, so I need the AAE/N.
I wish they had made those chips interchangeable. Smile

Hey, I can find some AAE/N here from Hong Kong though, some of them are dated 1977. I know there are rare so when I find few of them from a local distributor I bought them all.
