These are Blackjack games/calculators and carry the "Jimmy the Greek" branding (named after the American sports commentator and Las Vegas bookmaker Jimmy Snyder). The calculator can be switched between calculator and game modes, the latter allowing you to play Blackjack against the machine. In later models the display fascia is designed to suggest a Blackjack table. They have been available in a number of sizes and physical designs over the years.
