As Tom pointed out, Janus/Ada did full Ada 83 on MS-DOS by late 1987; and 
the Meridian people beat us by a few months.

Subset versions of Janus/Ada were introduced in 1981, and on the IBM PC in 
1982. There were other companies, too. All of these compilers were 
competitively priced for the time (several hundred dollars) -- the dirt 
cheap compilers (in more ways than one) came later (including versions of 
Janus/Ada for $99; indeed, that compiler is *still* in our catelog at $129).

Anyone who claims that lack of reasonably priced compilers had anything to 
do with the lack of Ada growth is just ignorant. There were lots of factors, 
but that is not one of them.

                                                Randy.
