The firmware/software needs data for calculations. No electrical contact, no chip, no information communicated to the cameras processing center.
Have you looked at pages 146 - 148 of your D60 manual?
Some more advanced dSLRs like the D7000 will let you enter the missing data for the manual lens. Thus these cameras have the minimal data needed for the necessary calculations. Just one of a couple reasons I bought a D200.
