I cannot believe how difficult it is to find an ASCII file with SIC codes! I am currently going through a conversion at work and needed to clean-up SIC codes we have collected throughout the years. I figured a quick Google would turn-up few thousand sites where I could download a text file. Nope.
Several searches later I was able to cough-up a couple of sites that had some SIC codes. The first was a list from the city of Milwaukee:
http://isdweb1.ci.mil.wi.us/gis/mprop/sic.dat
The second was a list from Great Britian found by someone looking for an ASCII file:
http://lists.evolt.org/archive/Week-of-Mon-20020415/109919.html
From these two lists and our 10 year-old production database I was able to create a list with 645 entries. I have posted it here for anyone to download. If you do download it I ask that you leave a comment with any SIC codes you have that that are not on the list.
