one way firewall?

I have little experience with firewalls.

Is it possible to set up a one-way firewall where data can be moved from a
windows 2000 computer to second system - a data host. (OS is relatively
unimportant - but likely linux), but data can't be moved from the data host
back to the windows 2000 system?

We have a computer that runs a scientific instrument. The system must be
tweaked to properly interact with the instrument. The system can not be
changed, patched or updated, thus it is vunerable to a number of windows 2000
security flaws, and can not be safely used on the net.

This makes getting data off the computer very inconvenient.

I am wondering if this system can be directly networked and firewalled to a
second system that is networked. Is it possible to get data from the Windows
2000 system to the second system, but prevent any data from getting from the
second system back to the Windows 2000 system. If any data is compromised on
the second system I don't want it to have any access to the Windows 2000
system.

It would be most convenient if the data interchange between the windows 2000
and the data host was smb

The second system could be used to provided a flexible number of data exhange
options - networking , cd dvd burning, memory stick etc etc,

Any suggestions?
