IIRC The FORTRAN runtime is common to all linked programs and I could easily envision it trying to set something up at startup. I’d have to ask Dr. Fortran to be sure (whom I’ll be seeing tomorrow if you want me to ask - while I was never part of TLG, my original Intel office was in back in ZK02, with them - they never moved when DEC sold them to HP, then Intel - so I’ve eaten lunch with them for about 20 years now, and the Friday TLG lunch lives on even after we all have retired).

The 11/70's FP board set is flaky, and it has been removed pending
repair. I had forgotten about that. But the "hello world" program
shouldn't use any FP instructions..?
I don't think I can get over to LSSM today, but I will be working
there tomorrow.
