NOS (New Old Stock) Texas Instruments SN76477 "complex sound generator" These are tested on a functional sound tester I designed many years ago and will be sent to you in working order. The tester was based on the TI spec sheet included here.
They are tested when you order them on that day, here in the USA and you will get them very quickly as well.
See my video which shows a quick example of me testing the chips oscillators and some frequencies (see below or CLICK HERE).
Please note: these are not pulls, and other than this tester they have never been used at all.
