It was a easy project to do, it was a lot harder when I had my WatFiv program get eaten by the CP/M upload computer, back in the 80s. I only had 12 compiles to redo the program from the listing, never did get it correct but I was the only one to have output for the program, I learned that from the teacher, after the final.

I agree with that, since we really don't know if the code even runs correctly.

I hope the code is correct, I'm not 100%, but 99% positive it is correct. All I do know is that the octal code should match, at least it does will the AsmPDP version, the Macro11 version, doesn't seem to compile an absolute address version. Which ever way you want to load the program is fine by me, I would have thought a binary would have been easier.

Yes, those are the lines I am referring too, even Bill said the PDF is incorrect and the 66 should be a 61 octal.
