Yes it does, though not the depth of information you're looking 
for.  You can get price (OHLC, volume, split-adjusted close) at 
http://finance.yahoo.com/q/hp?<params>

...where <params> includes:

s=symbol
a=startmonth
b=startdate
c=startyear
d=endmonth
e=enddate
f=endyear

Months are numbered from 0 to 11.  So for example:

http://finance.yahoo.com/q/hp?s=IBM&a=00&b=23&c=1992&d=01&e=24&f=1992

returns data from 1/23/92 through 2/24/92.

Yahoo returns it in reverse order, which is a pain, but you can 
copy it from the webpage and reverse it in Excel.

Or you can download a CSV file directly with a similar URL (which 
you can find on the history page displayed by the above URL):

http://ichart.yahoo.com/table.csv?s=IBM&a=00&b=23&c=1992&d=01&e=24&f=1992&ignore=.csv
