Texas Instruments Incorporated TM-71 Control Panel

Texas Instruments’ Burr Brown TM71 control panel is an operator interface panel that serves as a programming terminal for compatible Burr Brown instrumentation. The unit features an LED display and status LEDs, with a 25-pin connector for integration with older Burr Brown/TI hardware. In practice, the TM71 is described as a programming terminal with keypad, enabling direct input of commands and navigation of the instrument’s menus on supported systems. Variants such as the TM71B-22 (keypad/keyboard) exist and are listed as discontinued by the manufacturer, with a typical weight of approximately 0.7 kg. The TM71 family originated with Burr Brown, a brand now part of Texas Instruments, and listings generally present the device as an operator interface panel for legacy test and measurement equipment. Availability tends to be refurbished or used through specialty electronics distributors and used equipment dealers, reflecting its status as a legacy interface rather than a current, mass-produced product.
