The Free On-line Dictionary of Computing (30 December 2018):
Ada/Ed
    An interpreter, editor, and run-time
   environment for Ada, intended as a teaching tool.  Ada/Ed
   does not have the capacity, performance, or robustness of
   commercial Ada compilers.  Ada/Ed was developed at New York
   University as part of a project in language definition and
   software prototyping.
   AdaEd runs on Unix, MS-DOS, Atari ST, and Amiga.
   It handles nearly all of Ada 83 and was last validated with
   version 1.7 of the ACVC tests.  Being an interpreter, it
   does not implement most representation clauses and thus does
   not support systems programming close to the machine level.
   A later version was known as GW-Ada.
