    <larger>Al Qa'ida Casio Watch Timer on Perf Board

    Recovered in late 2002, this timer has a more complex interface that the simple Casio Watch Timer (Sheet 05706), but will not activate on the hourly chime. It has no safe-arm delay timer, as the opto-isolated detector circuit (Sheet 03340).
    *Time Delay: User programmable up to 23 hours, 59 minutes in one minute increments.
    *Power Source: Standard 9-Volt batteries for the detector circuit and detonator. The watch operates on its internal battery.
    *Anti-Tamper Features: None
    *Watch Type: Casio F-91W, but other digital alarm watches could be utilized.
    *Size: The printed circuit board measures 67mm x 62mm (2.6" x 2.4") with a maximum assembly thickness of 19.5 mm (0.8").
    *PC Board Substrate: Perforated, single-sided epoxy-fiber-glass experimenter board.
