XD Ada? Front end and debugger and various other bits by DEC, back
ends and runtime for 68k and MIL1750 originally by SD Scicon (who
became EDS Scicon, who are now part of HP). Still around, still
supported on VMS, therefore relevant here :)

There were/are others, but they're even more obscure. E.g. The name
Atego probably won't mean much, but that's where both Alsys and
Telesoft ended up. Verdix ended up as part of Rational which ended up
as part of IBM.

A marginally more comprehensive (but rather dated) list can be found
on the ACM's Ada special interest group website, at:
http://www.sigada.org/vendors.html
Beware bitrot: e.g. the Compaq entry links to digital.com ...

Meanwhile, SIGADA has even decided to change the name of its annual
conference, to High Integrity Language Technology. Rightly or wrongly,
that's how untrendy Ada is.
