Humm, the early Janus/Ada and Supersoft Ada ran on CP/M on Z-80's,
certainly before the 80286 was even invented. And we had Janus/Ada on
the PC in early 1982, and was well before the AT was introduced. (We had
one of the original PC/XTs, complete with sticker about not unpacking
before the introduction date [IBM had sent one to each dealer for
display purposes before the introduction of the XT.] - it's serial
number was something like 20000000003468.)

One can argue about what exactly consistutes an Ada compiler, but I know
Janus/Ada was out long before there even was an 80286, and we had
competitors at that time.

(And, if I still had that PC/XT, Janus/Ada 83 for MS-DOS would run on it
and compile and run the entire ACVC 1.11 test suite on it. We did
validate compilers on that machine under 1.9 and 1.10. So there
certainly is no need for a 80286 to implement a usable Ada 83.)
