Line 5:
This project dates back from the early
A few years earlier computer science had seen two marked evolutions : the Macintosh and the Ada language. Both were, each in its own domain, new worlds.
Strangely, those two worlds were quickly disappearing in their initial form
- The purity of black and white Macintosh was rapidly superseded by more powerful various machines, color screens, new os versions.
- Ada 83 stayed confined to some specialized area of high reliability software and twelve years later was "augmented" with Ada 95. This brought rare useful additions and a bunch of new possibilities which were more prone to degenerate the initial idea and the occasion of an added compiler complexity.
Being a Pascalist with a strong allergy to [[C]], Ada 83 was a real wonder and a compiler performance at the time. The inside Macintosh four volumes documentation were a thorough description of the Mac Plus system.
I then decided to see if rewriting a Mac Plus OS with Ada 83 was possible and brought some clarity and ease of software maintenance.

Time passing, CodeWarrior tools and machines changing, cross development became more difficult and tentative of rewriting with gcc C was done which was quickly abandoned being an horror story in maintenance and reinsertion in source code.
Then Gnat appeared, and being a new Linux user I saw that version 3.15 built on
A few trials were positive but development was not using a gdb stub and disquettes transfer for execution tests were cumbersome.
