I do remember time when 555 was too expensive and exotic for everyday use. There was standard way to implement same functionality with NANDs using all the gates in SN7400, but cannot find it now in the Interwebbs. Especially when Russians started to make 7400 look-a-likes with 2 millimeter pin spacing.
