navtronic 16 flight computer was developed by Specialized Electronics Corporation
(SEC) and introduced 14 LED-indicators to prompt the individual entry values.
The navtronic 16 was soon replaced with the navtronic 1701
adding a protection to the indicators on the keyboard panel.
Dismantling this navtronic 16 manufactured early in 1979 reveals a design based on a National Semiconductor Chip-Set MM5782 and MM57129 surrounded by some unknown chips with ITCxxx designation.
If we trace back in the history of electronic flight computers we discover: The Commodore N-60, the Heathkit OCW-1401 and this navtronic 16. All were introduced between 1976 and 1978, more than two years before the Jeppesen Sanderson avstar based on a Texas Instruments TI-35 appeared.
In 1983 Specialized Electronics Corporation (SEC) developed with the two Navigator and Explorer enhanced flight computers.
