In the movie "Hidden Figures", NASA receives an IBM 7090 in 1961. What is the subsequent timeline of the primary computing means for flight planning and orbit calculation?
Specifically, what was the computer used by NASA in 1975 during the Apollo-Soyuz program?
There is a widespread boastful claim During the 1975 Apollo-Soyuz Test Project the processing of Soyuz orbit parameters was accomplished by a BESM-6 based system in 1 minute. The same computation for the Apollo was carried out by the American side in 30 minutes.
The "BESM-6 based system" was, as a matter of fact, a combination of a BESM-6 with a newest multiprocessor data acquisition and processing system AS-6, using the same element base as BESM-6, yielding about 10-15 MIPS.
How old was the "American side" hardware in 1975?
