The first validated compiler for Ada that ran on the IBM PC was released in 1983.

The third validated compiler ran on the Western Digital “Pascal MicroEngine” running the UCSD p-system with 64K memory. The MicroEngine executed the byte code from the p-system natively, which was an interesting approach.

I think more research is warranted by you on this subject.

I’m not saying it wasn’t possible, I’m saying the larger ecosystem was never going to embrace a language that was as heavyweight as Ada. In 1983, most PC system software was written in assembly!

Janus Ada 1.5 ran on CP/M.
