Abstract: A game in which a game board is provided on which is depicted plural routes of attack against defenders of the Alamo. In the case of each attacker the game is played in three phases of play. The chances of the defender in defense of the Alamo are different for each of the three phases of play. An attacker must progress through the siege phase and through the assault phase before attaining the last stand phase. Each route of attack against the Alamo consists of a series of squares along which an attacker moves, certain of the squares bearing indicia indicating a procedure or happening to which the attacker may be subjected. The defender and each attacker is initially supplied with a plurality of markers each representing a person or soldier. Advances of the attackers are controlled by throws of dice, and loss of persons or soldiers in each defending and attacking force is controlled by throws of dice.

Abstract: Disclosed is an apparatus for providing non-destructive isolation voltage testing of circuit elements which includes a controllable full wave rectifier in series with the primary winding of a high voltage transformer, the secondary winding of which is connected to the circuit element under test. A current detector is responsive to a predetermined threshold current in the tested circuit element for providing a signal to control the rectifier to open-circuit the transformer primary winding prior to destructive breakdown of the tested circuit element. Opto-electronic elements are utilized in the rectifier to provide for the virtually instantaneous open-circuiting of the high voltage transformer primary winding.
