The 240 got rid of the Intel uPs for both technical and political

Not really. The VT240 have both a T11 and an 8085. (Not to mention the
8051 in the keyboard.) I can't really explain why it was so slow, but
back at the time, people were talking about the interaction between the
8085 and the T11, and a bad system design, as a reason.
The 240 and subsequent terminals never went as far in providing the
ability to add options as the VT100 did.
True. The original VT100 certainly was interesting in that aspect.
