MONSANTO MAN2815 8-Character 14-Segment Alpha-Numeric Display
Afficheur alphanumérique à LED
Alphanumerische LED-Anzeige

Intended for use in lightweight, compact intelligent data terminals.

From 1968-1979, Monsanto was the leading supplier of LEDs and opto-electronics. Monsanto did not set out to make LEDs, they were a chemical company, they made various chemical compounds, plastics etc. One of those compounds (crystals in this case) was Gallium Arsenide Phosphide (GaAsP), which turns out to be very useful as a semiconductor for light emitting diodes. This is what Monsanto set out to make, hoping to having other companies build the LEDs from the GaAsP they produced (which is how HP started into the LED display business).

By the late 1970’s, every one was making opto-electronics and LEDs either with patents licensed from Monsanto, or with processors of their own design. As profit margins dwindled, Monsanto sold off the division to General Instrument, exiting the LED business in 1979.
