I had the Janus Ada compiler running on a 386SX in the late 80s, and taught my then-15-year-old son to write Ada, while I was using DEC Ada at work. Later, there was the Meridian compiler than ran on standard PC hardware (still late 80s or before 1992, I don't remember exactly).. > > > Al > _______________________________________________ > comp.lang.ada mailing list > comp.lang.ada@ada.eu.org > http://ada.eu.org/mailman/listinfo/comp.lang.ada >
