Replacement for No-Slot Clock

["John E. Townsend" <utownje@lexis-nexis.com>]

The No-Slot Clock in my Apple IIe finally ran out of steam after years
of faithful use.  Is there someplace where I can get a replacement for
this chip?  For example, is the Dallas Semiconductor DS1287
(http://www.jameco.com/cfm/viewdesc.cfm?part_num=76646) an equivalent to
the NSC?  Thanks!
