Well, not exactly.  In the early days, Alsys developed a tool that translated
from a subset of Ada to PL/1.  This internal tool was written in PL/1.  The
first Alsys full-Ada compiler was written in Ada (really the subset) and was
compiled with the Ada-to-PL/1 translation tool.  The resulting compiler was
eventually used to compile itself and the Ada-to-PL/1 tool was abandoned.
