I also have no help to offer the OP, but if he is unsuccessful, he might be able
to use a different compiler. I recall TLD, Tartan, Intermetrics, GNAT, XD, and
XGC compilers for the 1750A. Tartan's Ada compilers were obtained by DDC-I, and
Intermetrics ended up absorbed by AdaCore. AdaCore doesn't claim to support the
1750A on its web site, so GNAT might have been an unofficial port. I don't know
about the availability of any of those, but they might be an option.

The 1750A was often used when radiation hardening is needed. I recall the RH32,
and this paper dated 2012

http://webee.technion.ac.il/~ran/papers/SurveySpaceProcessors.DASIA2012.pdf

lists a number of other RH processors and equivalents. It also seems that
current practice is to use redundant non-RH COTS processors or RH-By-Design
processors, which achieve similar tolerance of radiation at a lower cost than an
RH processor. Transitioning to such a system might be an option if staying with
the 1750A doesn't work out.
