The 16kB Language Card upgraded an Apple ][ from 48kB to 64kB. All later
Apple II came with at least 64kB - meaning that they all contain a "logic"
Language Card.

The Apple //c came even with 128kB - meaning that it always contains two
"logic" Language Cards.

Apart from that: ProDOS uses 13kB of the 16kB Language Card. So if there's
no "logic" Language Card, ProDOS won't boot at all.

Regards,
Oliver
