Is there a Test Tag 7 in the diagnostics?

From what I can gather, the available diagnostic tags on a fully-outfitted PCjr using only IBM hardware will be 1, 4-6, 8, 9 and G-P.
Diagnostics will also recognize the Rapport Drive 2, making a Test Tag 2 available. And since the BIOS can support 3 floppy drives, I figure Test Tag 3 would be present on a system with three drives.
But that still leaves nothing for Test Tag 7. What would that be for? The cassette adapter? Something that would have used the L port?
