From: Engineer on 8 Mar 2010 14:17 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". Does anyone know what these are? A google search came up with nothing relevant. Thanks for all replies, Cheers, Roger PS. address shown is fake for anti-spam, please use analogdino at(ta- boy) rogers dot(ty-as-they) com(e), suitably decoded. PPS. I hope this is not a double post - tried yesterday but found no sign of it on the NG.
