Hi, all. In a recently acquired pile of vintage junk (well not all junk, some good pieces!) I found a stick of 12 vintage IC's. They are all 14 pin DIP's marked "274 E16 L309", viz:
274 E16 L309 across the short dimension, one above the other. Does anyone know what these are? A google search came up with nothing relevant. Thanks for all replies. Cheers, Roger- posted
