We invite you to download the Scan/US working model 
and take it for a spin.  This full working model of 
the program lets you use every aspect of the 
product, including saving study areas and printing 
maps, and it comes with the complete online help, 
too.  The ZIP file is about 2 megabytes: when it’s 
fully installed it will take up about three 
megabytes on your hard disk.

How to install the Scan/US Working Model after you 
ftp it to yourself:

Place the scanwork.zip file in a new directory 
(just to simplify uninstalling it later) and unzip 
it using pkunzip.  It was compressed with pkzip 
2.04g.  It unzips to only about 2 megabytes, 
because the files are already compressed.
Then, from your Microsoft Windows 3.1 or Windows NT 
3.5 program manager, run the setup.exe program, and 
follow the directions from there.  The setup 
program will expand the files and set up a program 
group and icons.

How to uninstall the Scan/US Working Model:

The Scan/US working model program has a small 
footprint on your Windows system: to un-install it, 
just delete the c:\scanus directory and the 
scanus.ini file in your c:\windows directory.
