Avegon (NEC NT-7H)
What you see here are the earliest transistors made by NEC. Even more fun is that they are socketed, not soldered.
Those are obviously the ST-3B's on the right. At the left with their part labels facing away are the ST-12 transistors.
ST-16B - ST16A x 2 - ST3B x 2 - ST12 x 2 - [SD-46]
