Two Texas Instruments LED calculator displays.
One made 42nd week of '78, the second one, the 8th week of '79.
The wires inside the LEDs are silver color and not gold.
Borderline Telco?

The newer one, the traces are a bit corroded, when scrapped of the oxidation or battery shmoo, the gold is still there. Not sure the corrosion or shmoo matters?

Unsure.

Put both in telco. There’s not enough to bump them to any kind of custom quotes but definitely, as I posted on another thread, palladium. Combined with mostly gold trace and bonding, telco should be correct
