The first Department of Computer Sciences in the United States was established
at Purdue University in October 1962 according to
http://www.cs.purdue.edu/history/history.html

Not my impression. I think that ones originating from math
tended to have a strong abstract math flavor, e.g.
abstract families of (formal) languages, automata theory,
theory of computability. Numerical analysis contributes
but is not a focus. Applications (e.g. applied physics)
is small. UC Berkeley's computer science (in the
College of Letters and Sciences) started that way.

UC Berkeley had one of those, too, until they merged in
about 1972, and EE&CS became one department. The EE
contribution included things like "systems" and "optimization"

I guess we are in agreement about this: Atica does not sell here.

Learning Atica or mathematica is not usually a core objective in a calculus course.
At UC Berkeley, the history of the calculus labs seems to be that
if the instructor is a fan of some computer algebra system X, then
that is used. The next year it is CAS Y, etc.
For some schools the choice is made for a handheld graphing
calculator. Given the kind of usage .. a few commands, a few
plots, I suspect not much harm is done to most students.... since those
who go on to programming (or have previous programming
contact) will see other languages too.
