Yes, Acorns are quite seldom - especially in the US.

I will try to do so over the weekend.

My result:

Python 1.4 (Mar 20 1997) [C]
Copyright 1991-1995 Stichting Mathematisch Centrum, Amsterdam
>>> import multiarray
>>> a=multiarray.array([1,2,3])

array([1, 2, 3], 'l')
>>> a+1
Traceback (innermost last):
  File "<stdin>", line 1, in ?
ValueError: function not supported
>>> import umath
>>> a+1
Traceback (innermost last):
  File "<stdin>", line 1, in ?
ValueError: function not supported

You've already done a lot. Thanks,
