Don't forget Multics. It did have other uses, but if you had a Multics 
system, all software development seemed to migrate there.  Honeywell in 
Billerica had a Multics system which was used to develop much of the 
software for Honeywell's line of small systems: Level 6, DPS 6, etc. 
Same at large systems in Phoenix.

The reason this is important is that most of the people involved in 
developing Green, later Ada, including Jean Ichbiah, were Multics users. 
  So a lot of Multics concepts became part of Ada.
