It's an interesting point, but the VT102 works just fine so I don't think it is a problem. When I get my VT101 back I will have a third one to compare, it might help to decide what the norm should be. Despite the fact that they are three different models (VT100 hot, VT102 cool, VT101 still unknown) I think the fundamentals are pretty much the same.
