Photograph of schematics for a circuit board. There is no title on the page and there are four rows of circuits that are labeled "Relay", "Cam. Control 1", "Cam. Control 2", "Cam. Control 3", "Cam Control 4", and "Prod". There are two vertical rows of circuits on the right side of the board and then there is a rectangular component under these.

Photograph of schematics for circuits. The title box in the bottom right corner of the schematics reads "Sync Lock Schematic Diagram Model 3513-A1 D1202499 ..." and the box is surrounded by white paint. At the bottom of the middle of the sheet is a section of notes which reads "1. All resistors in ohms rated at 1/4 watt unless otherwise noted 2. All capacitors 1.0 or above in μμf unless otherwise noted and all capacitors below 1.0 in μf". There are two rows of circuits on the diagram and each of the individual components of the rows are labelled with a combination of numbers and letters. Above the top circuit and below the bottom circuit are words such as "Sawtooth Generator" "Phase Detector" "Power Supply" and "Sync Indicator" that label the functions of the sections. There are circles in the middle of the circuits at triangular shaped points.

Photograph of schematics for a clamper amplifier. In the title box in the corner is text that reads "Telemet Company Amityville, N.Y. Clamper Amplifier Schematic Model 3203A1 Drawn By T.D. Date 5/20/63".

Photograph of a schematic for a field camera control. There is a title at the bottom right corner of the page that reads "Figure 28. Schematic Diagram, Field Camera Control (W-302986 - Sub 10)". There are four rows on the schematic and the sections on these rows are labeled with a "V" and a number and have a word or phrase that describes the section's function.

Photograph of a schematic for a film camera. There is a title in the bottom right corner that reads "Figure 26. Schematic Diagram, Field Camera (W-305926 - Sub 7). The schematic has four rows of circuits and other components, and the sections of each row are labeled with the letter "V" and a number and a word that describes the section's function.

Photograph of a schematic for a field switching system. There is a title in the bottom right corner that reads "Figure 62. Schematic Diagram, Field Switching System (T-617838 - Sub 4)". Above this is text that reads "Unless otherwise specified: all resistance values in ohms - 1 watt. All capacitance values in microfarads. Tube number refer to corresponding numbers stamped on chassis near tubes with tube designation. Clockwise rotation of variable". There are three rows on the schematic and the sections in the rows are labeled with the letter "V" followed by a number and a word or phrase that describes the function of the section.

Photograph of schematics for a circuit board. In the bottom right corner of the image is a title that reads "Figure 22 - Schematic Diagram, TG-2A, TG-12A,Sync Generators (363995, Sub 3)". There are four rows of circuits and in between the rows are words such as "Clipper" "Regulator" "Rectifier" and "Genlock Relay", among others, to label the functions of the sections. The individual circuits are labeled with combinations of letters and numbers.

Photograph of a diagram of a linelock. There is a title in the bottom right corner of the diagram that reads "Figure 49 - Linelock Functional Block Diagram". The diagram features six blocks that are each labeled and the labels are "Linelock", "Frame", "Modulator", "Tone Wheel Phase", "Tone Wheel Velocity", and "Pulse Processor". Inside these blocks are smaller rectangles that are labeled with their functions.
