I sometimes wonder what "Turbo Ada" would have looked like, but I think it would have probably looked like later versions of Borland Pascal. Things like generics and exceptions would have taken some of the "turbo" out of the compiler and runtime -- the code generator didn't even get a non-peephole optimizer until 32-bit Delphi, it would have been too slow.
It might be nice to have Ada's tasks driven by DOS interrupts, though. I think GNAT did this.
