IC's XM101 & XM102

Does anyone know what the IC's XM101 and XM102 are? Is there a datasheet for these IC's? Vintage 1970's I think. Thanks.

** Why are you hiding all the relevant facts ??

How many pins ?

Where did you come across the numbers ?

On actual devices or on some old schematic ??

Any logos printed on the packages ??

What's the story ???
