Is this relevant? If these are calculators, I have never heard of this. Please clarify this.

Those are two Russian calculators. While the quality of the materials used in construction is questionable, the programming model is very good and there are many tricks possible that aren't in the manual (which is available in Russian or English) If you collect programmable calculators, you should have one or the other if not both in your collection.
