Vintage Toshiba BC-1010BJ Calculator and Blackjack Game

Description

Vintage Toshiba BC-1010BJ Calculator and Blackjack Game. Used, from an estate sale.  Shipped with USPS small priority box. Battery box looks clean.  Calculator part of the unit is functioning normally, I performed some addition, subtraction, etc on it.  Numbers light when switched over to the game function but I don't know how to use it to play the game as it also plays blackjack apparently. Takes 2 "AA" batteries. Comes with ORIGINAL vinyl (?) protective case.   Please examine the pictures as they are part of the description, this is not returnable.
