Agreed. The phosphor colour might be a better indication; AFAIK the early ones had white  phosphor CRTs while the later ones were green.

But everything could be upgraded; there was an upgrade kit that replaced the upper case half with the new keyboard and the newer bezel and label, and even the green CRTs were available. On the other hand, especially in schools, old motherboards were often replaced with new ones.
