Welcome to Nikonians! The SB-27 was designed for Film cameras using Film TTL Flash Control like your N70. The D60 uses i-TTL Flash Control which is not compatible with Film TTL Flash Control. Therefore to use the SB-27 on your D60 you will be limited setting the SB-27 in Non-TTL Auto Flash Control (I am not sure it can be set with the SB-27 mounted in the hotshoe of a DSLR) or Manual Flash Control and the Camera set in Manual Exposure mode and Manual ISO mode.
