Installation problems on Macintoshs:
 Q: I unstuffed the file, got a password, and the
installer seemed to be running fine until it was about 75 percent done, when it
suddenly said, "Cannot find file: Mathematica,"
A: Is a bug in the installer. Try to make a custom install where you install
each component seperately.
An other hack (thanks Darren!) is to
change the name of the "Mathematica 4.1" application to "Mathematica" and
then do the installation.
 Q: During the installation, I get an "error of type 39".
A:
 mac_mma41.sea thinks it's a selfexpanding archive,
but it's not. Expand it by draggin it on to the
Stuffit Expander icon.
 The error can also happen, if you install from a medium different than your local harddrive.
 The error can also occur if an older unstuffing software is used.
You can download the latest version of Stuffit Expander
here.

How do I print at the Science Center? 
See the
Printing guide of HASCS. Note that you need to have a
printing budget . 
I tried to print my notebook but there is no printout. 
1) You might have no printing budget. The printer would spit out a page telling this. \\
2) You might have written the notebook to a PS file on your computer instead of sending it
to the printer (you can chose so at the printing dialog box).

I want to save paper. How do I print out only a part of the notebook. 
Chose "print selection" instead of "print" in the Mathematica notebook. The selected cells will be printed.
Alternatively, open a new notebook, cut and paste the part you need to turn in into
the new notebook and print that out.

I have problem running Mathematica
on a G4 Macintosh in the Basement of the Science Center. At the
first evaluation, the program asks me for a "Math Link program to Launch".

Mathematica runs on a server. It can happen taht the program can have problems
with finding the Math kernel (which is a seperate program).
In the window asking for the Math Link program, choose
"General Software/Math & Statistics/Mathematica 4.0/Executables/Power Mac/Math Kernel".
It will then take some time until the Kernel is fetched from the server and the first
evaluation can be done.

How do I see which printers are available under Unix 
Type at the Unix Promt
lpstat a
To print a PS file "file.ps" on Printer scb11c, type
lpr Pscb11c file.ps
To see, what is in the queue:
lpq Pscb11c
