Hi all.
I'm quite new to the world of electronics, but when I showed interest my father gave me a bunch of old ICs and stuff he had collected in his days as a TV repairman. Among dozens of useful stuff I found a couple of tidbits that I haven't been able to identify. Picture (of admittedly inferior quality) attached. Can anyone offer some insight as to what these things are?
The leftmost one is a NEC "PRAD-2" chip with 8 strangely spaced legs.
The middle one is a golden IC marked with "S5400F" (I'm suspecting that this might be a quad NAND gate)
The rightmost one is a strange little thingy that came with a small plastic cap with two holes in it.
Any takers? I can dig out a better camera if anyone needs or would like a closer look.![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
Thanks.
