Termatrex Card Reader

<< >>
The Termatrex card reader has a metal case painted green with a translucent white plastic top. The case contains fluorescent lights. A yellow-edged template and plastic rule are atop the box. A grid of lines allows one to read the number corresponding to the location of a hole on a punched card, or set of punched cards, below the template. One then could refer to a report filed with this number.
A mark on the rule reads: TERMATREX INFORMATION AND DATA SYSTEMS. Another on the upper right corner of the box reads: JONKER. The Smithsonian propertay tag reads: 80089.
For a fuller description of the system, with references, see the description of the drill at 1993.0132.01. For cards, see 1993.0132.03. For documentation, see 1993.3065.
