Here are the archive links to two posts you made with detailed
configuration data:
<http://astro.umsystem.edu/atm/ARCHIVES/JAN99/msg01448.html> and
<http://astro.umsystem.edu/atm/ARCHIVES/JAN99/msg01389.html>.
Someone on the atm list threatens to make one of these once a year or so,
so the topic comes up periodically. If anyone's actually done it besides
the author of that article (Endemann is the correct spelling I think)
they're keeping it quiet though.
