Unknown chip in flatpack package soldered on a board. Comment from Brad Thompson: The chip ... is quite likely a Sylvania SUHL ("Sylvania Universal High-level Logic") IC, an early TTL family. The PC-board frame allowed easy breadboarding and handling for test purposes. As a co-op work student in the early 1960s, I actually constructed a breadboard with a few of these ICs!
