Fast delivery but the IC are all from different manufacturer and rebranded over as UM6522A with a batch lot ref of 89345. I'm not judging a product fro the label but if you sell a remarked one is to be told in your auction. Better see these IC as Rockewell or Synertek and not rebrand as UMC ...
The chips came in a protective pad. They are in a very good shape. Still not tested, but I'm confident as they look really good.
Oops ! My bad ! Because the comments can't be corrected, I post here an update : The chips came *face to face, wrapped in plastic - but there is just 2-3 slightly bent pin - so it's still OK for me*. They are in a very good shape. Still not tested, but I'm confident as they look really good.
