       Sharing the introductory post for a chip-tune synthesizer I wish to
       build.

       | Also there is zero chance that some of them have bottom-marked
       | lot codes and some don't, given the same top date/facility code.
       | Dead zero. And the cavity IDs on the DIP molds should be the same
       | style, not randomly mismatched.... I'll stop here, but this is
       | classic gray market remarking stuff. These are random old chips
       | that have been relabelled.
       | 
       | They may well still be AY-3-8910s in there -- the gray market is
       | _very_ creative -- and may well be usable for you, but be
       | cautious. If they look like they 're misbehaving, the chances are
       | much higher than usual that it's not your fault.

         | Yeah it's strange, they've clearly been relabeled and maybe
         | only the top two I tested are real. Even if that is true I
         | still have a couple of new toys to play with. I'll test the
         | rest tomorrow.

         | that I can tell are genuine than "new"/"refurbished" examples
         | like the ones in this article.
         | 
         | I love the AY-3-8910 and I've bought chips that were remarked
         | in this fashion, fortunately they all worked ok and sound like
         | the real deal.
