I do not know the exact year of my R6581, but most IC datecodes are from 1995 and 1996, therefore it was most likely build in 1996

there is a stamp "9640" on some of my boards
If your boards are newer, there must have been an change and the C215 Problem was not solved, but instead created/introduced with this change.
