System information

General Description
The Black Widow is a Pentium-class microprocessor controlled dart
machine. It consists of three main subsystems: the sealed switch matrix
scoring system, the central processing unit (CPU), and a video display.
The machine is completely serviceable from the front. All major machine
components are accessed by unlocking the front panel and swinging it
open.
Both the video monitor and main CPU are removed for service by discon-
necting the associated cabling and sliding them forward, out of the cabinet.
The dart head assemblies are accessed by removing the four screws hold-
ing the web to the backboard.
Power Supply
The Black Widow uses normal line voltage (115vac/60hz) for the target illu-
mination lamps and to power the video monitor. The CPU contains a power
supply assembly which converts the line voltage to the direct current volt-
ages necessary to operate the machine’s low voltage circuits.
Main CPU
Main Board
The mainboard contains the main processor and memory that control all
machine functions. The main processor communicates with a number of
subsystems to achieve this purpose. Subsystems are controlled by various
expansion cards installed on the main board. For technical information, refer
to the Mainboard Manual that was shipped with the unit.
