Well, the actual machine code is very weird; it was weird enough that they 
provided our project with a guy whose main job was to figure out what was 
happening at the lowest level and feed it back to the rest of us working in 
the "normal" world.

So far as I know, no one ever used the Ada 95 compiler we built for Unisys. 
(I hope not, 'cause we never got paid for one. :-) It was a lot harder 
project than we predicted and it didn't get done fast enough for the 
prospective customers. A very interesting project, though.

Dunno. I haven't heard from any of that group in many years.
