As used on the Apple II+, the 2513 Chargen has the following layout:

Uppercase
Punctuation & Digits
Uppercase
Punctuation & Digits

While 7 bit ASCII has

Control Characters
Punctuation & Digits
Uppercase
Lowercase

So if you store lowercase to the screen it becomes Punctuation &
Digits.
I know that KEYIN on the II+ maps lowercase to uppercase, I will have
to check what COUT1 does.
