Housing, Skid Control Circuit Board - The housing was for the final version of a truck (tractor) skid control circuit board. The design was done in 1973.

The board was mounted in the housing which was mounted on the truck chassis. The project was done for Kelsey-Hayes for use on Ford trucks. It was not put in full production because the Federal requirement for truck skid controls was canceled.

Circuit Board - This board was made in early 1962 and contains some of the first silicon monolithic integrated circuits.

The board was designed and manufactured by the Industrial Products group of the Apparatus Division in Houston. This group subsequently evolved into part of Data Systems. We have been able to identify the application for which the board was intended. However, the date codes of the transistors and the symbolization used for the IC's are good indicators of the manufacturing date. Symbolization of the early IC's was by hand with the number shown by color code. These units are type 240's.

Circuit Board, Truck/Tractor Skid Control - The item is an engineering board of the final design for the truck tractor skid control system. The project was for Kelsey-Hayes and was to be used on Ford Trucks. The work was done in early 1973.

This board was used by engineering to check out part of the final design and processing. Hence, it does not represent a finished printed wire board of the final design. A completed board was mounted in a housing (P00221) which was mounted on the truck chassis. Because the Federal requirement for truck skid controls was canceled, the project was not put into production.

Circuit Board, Automotive Skid Control - This board represents the initial version of the circuit board for the Kelsey-Hayes Automotive skid control system. From the device date codes, this board was built in early 1972.

Discrete devices were used in the design which was done by Control Products with Semiconductor Group participation in 1969. The skid control was for use on Ford cars and trucks.

Circuit Board, Automotive Skid Control - This board represents the final design of the circuit board for the Kelsey-Hayes automotive skid control system. It was built in February-March, 1973. The skid control was for use in Ford cars.

This design by Control Products with Semiconductor Group participation utilized three integrated circuits. Satisfactory performance of the skid control system was demonstrated, but it was not put into full production. Repeal of the Federal law requiring large trucks to be equipped with such a system deleted the major market requirement and resulted in cancellation of the project. However, some of the top of the line Ford cars were equipped with skid control as an option.

Circuit Board - Minuteman II represented the first major production use of integrated circuits.

This double side multi-player board is typical of those used in that system. The board design was an innovation at the time of the design of the system - 1962-3. This board was probably used in later system and contains all TI circuits. TI was sole source supplier for about the last half of the program. Minuteman II production period was 1963-67. The Minuteman guidance system was designed and built by the Autonetics Division of Rockwell International.

Circuit Board - Minuteman III was the successor to the Minuteman II, and the guidance system was a major user of integrated circuits. The IC's utilized dielectric isolation technology for radiation tolerance.

Although dielectric isolation was applied to the chip design, Autonetics and the Air Force directed that TI use the same geometries and metalization system as used for Minuteman II. Electrical interchangeability between MM II and MM III circuits was maintained. Minuteman III production period was 1968-77. The Minuteman guidance system was designed and built by the Autonetics Division of Rockwell International.

Circuit Board - Minuteman II represented the first major production use of integrated circuits.

This double sided multi layer board is typical of those used in that system. The board design of the system-1962-3. This board also contains two TI bilateral germanium alloy transistors. This is an early board showing some rework before it was scrapped. The Minuteman guidance system was designed and built by the Autonetics Division of Rockwell International from whom this board was received by Randolph.

Related material in collection: Z00145, 146. ATTACHMENT: A check at the source at Autonetics indicated that this board was built in late 1965 or early 1966. Date code on the transistors fit that timing. All but one of the IC's left on the board are from TI. The IC's do not have date codes but have individual serial numbers. As a part of the program reliability requirements, records were kept by serial number so that a complete processing history of each IC from start to shipment was available for each device.

Circuit Board, Tercom System - The item was one of the first applications of integrated circuits in production equipment- 1962-63. It was used in equipment built by TI for LTV.

This item was part of the original S/B Lobby display. The system was a Marine Corps airborne mobile flight control equipment. TI used series 51 and custom variations of catalog devices. Their assembly into subsystems took the form of plug-in boards an encapsulated plug-in modules which offered size and shape advantages in meeting the packaging requirements. Also shown is an unsealed example device. The original display lists Emil Skocpol and Charles Phipps as contributors.
