When McDonnell Douglas Aircraft
modified the original AV-8A design of the Harrier to extend its operational
life, it was renamed to AV-8C (Harrier II).
In the same timeframe Texas Instruments replaced the TI-58 used in the UMSC Harrier calculator with the TI-58C and consequently this UMSC AV-8C calculator was introduced.
In the meantime the Harrier II was replaced with the Harrier II Plus or AV-8B.
The
innovative TI-58/TI-58C/TI-59 calculators were the perfect base for a lot of
customized products. This one was used in the 80th by the USMC
(United States Marine Corps) to calculate Takeoff, Landing and Flight maneuvers.
The idea behind these products
was the novelity of the
Solid State Software Modules™ with up to 5000 program steps. This software was
written by the SW-engineers of the McDonnel Douglas Aircraft
company and programmed into the
modules by Texas Instruments.
The
customized keyboard hides most functions available on the standard TI-58C and
allows only access to the basic calculation functions and the programmed
functions of the AV-8C module.
