Richard Riehle asks

1) I have heard a rumor that the first Alsys Ada compiler was
   written in PL/I. True or False?

     False, the first version was written in Ada, the bootstrap was done
     using a translator that translated from a subset of Ada to a subset
     of PL/1 (which is what gave rise to rumour you heard). The PL/1
     translator was thrown away as soon as the compiler was bootstrapped.
