Are there technologies (materials, components, systems, or software) that continue to be manufactured in the United States for space applications, even though they would otherwise be considered obsolete?
To clarify the question:
The technology must at some point in history have had some non-space purpose. Yes, there are lots of things custom-built just for NASA, but that's not what this question is about. Military aircraft would qualify as a non-space application.
All non-space applications should be discontinued. That's what makes the technology "obsolete".
The technology continued to be purchased for the space program despite its obsolescence in other applications.
Because the U.S. space program is in transition, examples from the shuttle era are acceptable, if they were already obsolete at the time they were used in the shuttle program. However, modern examples are preferred.
"Space program" primarily refers to NASA, but DoD and private programs (e.g. SpaceX, Bigelow) would also be relevant to this question.
This question is similar to my previous question, "Does Russia still manufacture parts for their space program that would otherwise be obsolete?", except applied to the U.S. program. Answers will therefore not be the same for both questions.
update: The question is not intended to be limited to computer technology. For example, one answer to the Russian version of the question was a change in fuel injectors.
