While I don't have access to my CVS repositories, I do have access to my cvsync.conf file, which shows all the repositories I keep. If you wish to copy/paste/edit it, you'd only require the "openbsd-cvsroot" repository collection.

config {
    hostname anoncvs3.usa.openbsd.org
        compress
        collection {
        name openbsd-cvsroot release rcs
        prefix /cvs
        umask 002
        }
        collection {
        name openbsd-src release rcs
        prefix /cvs
        umask 002
        }
        collection {
        name openbsd-ports release rcs
        prefix /cvs
        umask 002
        }
        collection {
        name openbsd-xenocara release rcs
        prefix /cvs
        umask 002
        }
        collection {
        name openbsd-www release rcs
        prefix /cvs
        umask 002
        }
    }
