Diode & rectifier set 2N3899 1N1513 ir vtg hp computers


This is a set of seven items-two are diodes: RCA 2N3899, IR 1N1513-I think the others are Rectifiers, but please feel free to correct me if I'm wrong: two IR '69 0943,' Erie 1500 M; two items that are the same but he markings are worn off or non extant. These were acquired from the estate of a former HP Engineer who had worked on the early HP Computer and Calculator development. They are likely from Computer or Calculator projects.
These have light overall wear-some smudging to the sides.
