G00282   NMAH Catalog Number 1987.0487.004
 
TI number: G00282
Camera Electronic Control Module - This module controlled the shutter, flash and motor in the SX-70 camera. This item represents initial design version. From the type of potting compound compared to that on other samples in the collection, this was probably from an early development lot.

The IC's, transistors and diode were mounted and bonded on the ceramic substrate and then covered with a potting compound for mechanical and moisture protection. First prototype modules were shipped in February, 1972. This item was in a Polaroid file assembled by Prentiss (Buzz) Selby for the TI Historical Project. That file is in the TI Archives.

G00283   NMAH Catalog Number 1987.0487.005
 
TI number: G00283
Camera Electronic Control Module - This item is a collection of modules from 1972-3 production representing the first design version.

Close examination shows various minor differences which represented efforts to improve performance or fabrication. A critical fabrication step was adjusting each module by laser trimming the resistors. One module in the collection shows the semiconductor chips without the potting compound.

G00284   NMAH Catalog Number 1987.0487.014
 
TI number: G00284
Camera Electronic Control Module - This module controlled the shutter, flash and motor in the SX-70 camera. This item represents the second design version.

In the second design version, the deposited resistors were not required which eliminated the trimming. Two IC's replaced the IC's, transistors, diode and resistors of the initial version. On of the modules, the IC's are sealed in a clear plastic for display purposes. Also, there is a slight difference in the interconnect pattern on the two items.

Z00287   NMAH Catalog Number 1987.0487.016
 
TI number: Z00287
Camera - This camera was one of the early production SX-70's which was in late 1972. The Electronic Control Module (ECM) and the Motor Control Module (MCM) were designed and built by the TI Semiconductor Group.

A partially used flashbar and filmpak were received with the camera. This camera is one of several presented to TI managers by Land shortly after the camera was introduced. Adcock was in charge of the program for development and initial production. TI started work with Polaroid on the controls for the SX-70 (Advanced Camera) in late 1968 and worked in parallel with the camera design at Polaroid. Prototype modules were shipped in February, 1972, and the camera was released in time for Christmas, 1972. See LIFE, October, 27, 1972, and SYSTEMS ENGINEERING, February, 1974, articles on the SX-70. A copy of each is in the Artifact Historical File. From correspondence in Haggerty's Polaroid file in the TI Archives, this camera was received in December, 1972. A letter from Haggerty to Land establishes this date. Conversations with others revealed that Land and several other Polaroid executives visited TI and presented several SX-70 cameras. Identified so far as recipients were Adcock, Bucy and Haggerty.

G00197   NMAH Catalog Number 1987.0487.017
 
TI number: G00197
Camera Electronic Control Module - Module is one from the first day's production at the TI Taiwan plant - August 22, 1975. The module was used in the Polaroid PRONTO camera.

Project CUE was the code for the program. TI was sole source for Polaroid, with all production being done in Taiwan. The module was in production through 1981.

G00317   NMAH Catalog Number 1987.0487.076.01
 
TI number: G00317
Television Camera Tubes - The TIVICON was a vidicon tube using a silicon diode array for the imaging target. This example was the shortest of the three models built by TI. TIVICON was the only vacum tube product ever built in production by TI.

TI began development of the TIVICON in mid 1967 for use in a Forward Looking Infrared detector equipment (FLIR). The silicon diode target development was based on work done at Bell Telephone Laboratories as part of their Picturephone program. Although some parts were purchased, the tube was manufactured by TI. The first prototype tube was delivered to TI Equipment Group in the first quarter of 1968, and the first Mil Spec tube in the fall of that year. Production continued into late 1972. However, production of the silicon diode targets continued until about 1980. Techtonix had found their signal retention characteristics well suited for use in a storage tube system. The TIVICON also found an application in low light level security TV cameras, and a number were sold to outside cutomers. In the progress of semiconductor technology, charge coupled device (CCD) imagers were developed and became more cost effective in the applications using the TIVICON.

C00481   NMAH Catalog Number UNKNOWN
 
TI number: C00481
UNKNOWN - This FLIR is the oldest version of a FLIR known to exist and was built in about 1971. The first FLIR ever built was by TEXAS INST. in 1964.

Consists of an infrared optical system with germanium lens which collects & focuses the IR signal on 180 IR detectors which are cooled by a helium refrigerant cryogenic closed cycle system. The detectors feed 180 amplifier channels which power 180 light emitting diodes. A rotating mirror ass'y views the LED's and a TV camera views the rotating mirror ass'y and the resulting image is shown on a cathode ray tube. The resulting picture appears similar to a black & white TV picture of the area being scanned. The difference is that heat gradients cause the image & that this image can be obtained even if the area is in total darkness.
