Rear View of Master Control Panel Wiring, San Francisco State College
About This Item
The back side of a master control panel shows exposed wiring, terminal connections, and control components used to manage and synchronize analog systems. The image highlights the internal architecture of electronic equipment and the manual configuration required for operation and experimentation.

- TP-ATA-1872
- Context
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.
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
