That is the "h" segment for P3/P4.
Group B "h" segment is controlled by Z16, pin 10.
Since the chip was socketed, prior rework is always suspect. Buzz for continuity. Perhaps replace Z16.

Quoted from Next_Level:

Chris, I'm sure you know this, but I want to be explicit for the next poor bastard working on a System 80 game that might find this post in a search.

I got a chuckle out of this Next_Level ....

Quoted from Next_Level:

Now I'm off to the Great Plains Electronics for some new 7404s.

My favorite place to shop.
