Alsys decided to write in Ada from the very start (they believed in the advantages of the language, unlike some other vendors who even today are writing Ada compilers in other languages :-) That meant they needed a bootstrap path, and the path they used was a temporary partial subset translator that translated the Ada into PL/1, so they were using PL/1 not as a source language, but as an intermediate object language.
