Does anyone have a reference to the rev 7 Apple ][ that has lower case that the article refers to? Apple’s first professionally built computer was the Apple ][ which from rev 7 onwards added lower-case letters. The Apple IIe (1983) and onwards had the lower case characters that are shown in the image for the the Apple II (1977). https://en.wikipedia.org/wiki/Apple_IIe#New_features https://en.wikipedia.org/wiki/Apple_IIe#New_features
