Video Monitor
8.2 General Description
The video monitor is capable of operating in up to 1280 x 1024 pixel resolution,
although the resolution used for game-play in the Aristocrat Video Gaming Machine
is 640 x 480 pixels. The model is a short neck CRT that operates with a dot trio
spacing of 0.26mm and a colour temperature of 9300°K. Operating temperature is
32°F to 131°F (0° to 55° C). Net weight is 37lbs (17kg).
The major components of the video monitor assembly are:
the cathode ray tube (CRT),
the video monitor printed circuit boards (PCBs) and
the video monitor frame.
The CRT and video PCBs are all mounted onto a common metal frame that slides
along the game display shelf into the cabinet (refer to Figure 8-1). The video monitor
assembly is secured in place by a single screw, inserted from the underside of the
game display shelf.
The slide-in frame enables the video monitor assembly to be removed and replaced
easily, and also to connect to the rest of the machine via a single, self-aligning, multi-
pin connector on the back of the frame. This connector transmits the monitor power
and the video drive signals from the video interface.
The PCBs associated with the monitor assembly are:
Picture Control PCB
•
Monitor Main PCB
•
CRT Neck PCB.
