For DOS
TACT from the Centre for Computing in the Humanities in Toronto.
Good facilities, but only useful for corpora upto about 1 million
words. Their WWW URL is:
http://www.cch.epas.utoronto.ca:8080/cch/tact.html
For Mac
There's something called Free Text Browser which is available via
ICAME. Not too limited on corpus size as far as I know.
I think it's available at;
