In issue 7'95 the computer magazin c't published an
article "Das Ende des Bleistifts" in which
computer algebra systems are compared. They tested the MS-Windows
versions of Derive 3, Macsyma 2,
Maple V.3, Mathematica 2.2 and Mathplus.
Also AXIOM and MuPAD were mentioned but their
test results were not published, because both had no MS-Windows
user interface at that time.
Note that MuPAD is the only non-commercial system in this test.
The Windows version of MuPAD is
now available.
