Notes
from the Hubble Project team, January 4, 1999
With
the installation of the 486 Advanced Computer during SM-3A,
the DF-224 flight software project has come to an end. Although
it was a 1970s-vintage computer, the DF-224 served us very
well through the years. With the addition of a 386 coprocessor
and additional memory during the First Servicing Mission in
1993, the DF-224 provided flight software services to each
of the other HST subsystems right up to its replacement on
December 23 of last year.
When
I began working on the DF-224 flight software project in 1991,
I was very much impressed with how clearly and efficiently
the software had been written. The original authors set of
a standard of excellence to which the DF-224 flight software
team has always striven to aspire.
On
behalf of myself and the rest of the DF-224 flight software
team, it has been a pleasure working with you, and we look
forward to working with you again in the future on the new
486 flight software project.
