Section 1 — System Overview
Video Processor Frame
The Zodiak Video Processor frame houses most of the system electronics,
with horizontal slots that hold individual system control, video routing,
and signal processing modules. A built-in fan system allows cooling of the
frame. A fully loaded 3-M/E system is shown in
Figure 5 .

The Zodiak system has been designed for easy maintenance. Modules and
power supplies can be removed and replaced safely from the front of the
frame with the power on, simplifying troubleshooting to the module level.
The standard 2.5-M/E Zodiak Processor frame includes the following:
• Floppy disk drive,
• Control Processor/Still Store/DSK module,
• M/E module (M/E 1 and M/E 2),
• Input/Crosspoint/Sync Generator module,
• Two Video Processor frame power supplies, and
• Air filter and Fan module.
The standard 3-M/E Zodiak Processor frame includes the same modules as
the 2.5-M/E system in addition to the following:
• M/E module (M/E 3), and
• Redundant power supply.
The rear of the Zodiak Processor frame provides the reference, video and
system control connectors for the system.
