If you carefully clean the top of an IC and hold it up to a light so that the rays just glance off the surface, it is usually possible, with a magnifying glass, to see where the number etc was printed, clearly enough to read it. I have done this even when there was apparently no paint left on the IC. Regards, Chris Chapman __________________________________________________________ Public Seismic Network Mailing List (PSN-L)
