Yes, these folks do not market like the commercial side but there is a small industry supplying obsolete parts. They are not usually not focused to sell to the public. Sometimes, they just hunt around for NOS stored in some forgotten warehouse, then they test components to insure like new

Our life cycle management program assures you of a dependable, quality source of obsolete IC's forever. No mention that the price may go up exponentially each time you ask for a quote, and don't try to buy two dozens. They probably won't make a run for much less than several thousand pieces, and
