|Circuit Board - 1962
TI number: L00231
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.
