Well, you've got it right generally, but I know that the "main" computer
is a 68020 on Ariane-5, and the Inertial (SRI) computers are also of the
68k series. I happen to know this because we provided the Ada compilers
for both. The "main" computer runs a full-Ada runtime, whereas the SRI runs
a "zero-byte" (well, not quite) runtime, the SRI team having their own
"RTOS".

However, the SRI team have recently completed their move to ERC32 (i.e Rad-Hard
SPARC). Starting this fall, all new SRI flight units will be ERC32-based.
