1985 Texas Instruments stopped the production of the TI-55-II
due to the terrible keyboard and introduced the TI-55-III
with a reliable far-east style keyboard.
As a result the original prostar Flight computer was replaced with this 2nd design using the new housing with the old electronics.
This prostar was the last Jeppesen Sanderson Flight computer based on a TI calculator, the Techstar uses an original design.
Nevertheless got we four exciting products between 1980 and 1986:
|Jeppesen Sanderson Flight computer||Texas Instruments calculator|
|avstar (1980)||TI-35 (1979)|
|avstar (1986)||TI-35-II (1985)|
|prostar (1982)||TI-55-II (1981)|
|prostar (1986)||TI-55-III (1985)|
