I say it is NOT, because at those speeds you still have to place it by
hand anyway. Here is a good link to prove that point.

to meltdown - they ran too fast. What is the problem is you have
Mega-transitors
in the modern machines - nothing like a PDP-n that had a nice simple
logic and control design.
