As the name of the program says, this is an elliptic curve
calculator. It graphs elliptic curves, does arithmetic with points on
elliptic curves and computes properties of elliptic curves.

You can enter the Weierstrass coefficients, do some arithmetic with
point on the curve, as well as factor the discriminant and the
j-invariant, and compute the conductor.  Computations are done with
50-digit (internal) accuracy.

There is also a graphing feature, but it is extremely slow even on a
reasonably fast machine.  There is no users guide, but there are two
pages of help available from the help menu.  With the recent interest
in elliptic curves arising from factorization methods of integers, an
update to this program would be welcome.

In spite of its age (released in 1987), the program runs on all the
systems that I have tried, including system 7 in 32-bit mode.
