So I was off on my recollection of the timeline on one of the two specs.
AFAICT this has no bearing on implementation enduring for the life of a
product. Lucky you who never had DDC die on an otherwise perfectly
functioning unit, but in the real world it happens, and not so rarely. Same
for discovery that it never worked right until after the warranty expired.

Out of a significantly larger quantity formerly in my possession, I still
have 3 examples of a single best-seller model of major brand CRTs
manufactured during transition from Tualatin (PIII) to Willamette (P4). Of
the 3 still here, only one has had its DDC endure, and less than 50% of those
I had left here with DDC working.
