Rear View of Master Control Panel Wiring, San Francisco State College (Alternate View)

 Wiring Harness

• The tightly bundled wires leading to a central terminal strip is typical for master control panels—allowing external connections to be routed cleanly from the inside.
• Those bundles likely connect to:
• Other simulation equipment
• Signal amplifiers or conditioners
• The CRT monitor or oscilloscope interface
• The backs of panel meters can be clearly seen, as well as trimpots or resistors soldered directly to terminals—used for fine calibration of each circuit.

 Terminal Blocks

• The bottom section houses neat terminal screw strips—textbook 1960s analog control design.
• Wires are color-coded or labeled for system interfacing—helping operators trace signal paths for diagnostics or experimentation.

 Label: “POLAROID”

• That small label in the corner ("POLAROID") may indicate the metal case or box was repurposed from a Polaroid equipment housing or lab tool.

 This would’ve been part of a student-visible demo or instructor-led experiment, allowing:

• Real-time manipulation of analog variables
• System monitoring and fault simulation
• Possibly even troubleshooting exercises for control systems
