Honest company run by good guy Randy Brukhard, who is a long time 
participant on the newsgroup. Unfortunately, not available on the 
platform I wanted it for. Hobbyist-friendly.

There was a recent announcement here in the newsgroup, unfortunately 
without any pricing. Pricing is also not found on the PTC website. In 
the past, Aonix did have a hobbyist compiler but I haven't seen it for 
years.

Huge money and the salesman I spoke with displayed significant disdain 
when I turned out to be an individual rather than a company. Did not 
disclose pricing. However, in speaking with another participant 
off-list, I was given some sense of the pricing.

Not sure if anything past '83 is supported. But do check if you're 
interested. I believe JOVIAL is also available from DDC-I.

It was sold to a company in Washington, D.C. which I believe still sells 
the Ada 95 compiler. I don't believe they support any additional 
standards after 95. I'm sorry, I can't remember the name.

I attempted to get a hobbyist distribution to run on the Hercules 
z/Architecture emulator (which also supports MVS, MVS/ESA, and OS/390) 
but was not successful. Appeared to be a reasonable guy and the product 
was well integrated in MVS/ESA but probably not generally useful to most 
people in this newsgroup. If it is, would be worth identifying the 
company and starting a dialog.

Lastly, we should mention gcc-ada which was still out there for Linux 
and Solaris last I looked, and even for some unusual platforms like 
Solaris SPARC. The SPARC platform maintainer was very helpful and I got 
a copy at some point, I can't remember but I think around gcc5. There 
used to be gnat 3.15p (last non-GPL) release but it was cruelly excised 
from all servers and download sites when Adacore happened.

We should note, GNAT / Adacore were created on the backs of American 
taxpayers via a grant to New York University. Unfortunately, the 
taxpayers got the shaft and a profitable business was born to continue 
the fun.
