Ah, not quite the final. I found a NOP report on the AOS program by Jim Horn (as he thought there had been).

NOP corrections to AOS program

Here's my version of the AOS raw file with the corrections made. I think I did them correctly. I also realized there is no need for a separate CLR or CL label (Clear). The AOS label itself can simply be the global label for "clear". LBL AOS LBL a SF 27 etc. This saves some bytes. It is at 350 bytes now.

I still don't think this addresses the CHS functionality that we question. I would think "CHS" would make + or - but it seems to do nothing.

With all of these changes, I think we have 11 spare bytes if my math is correct at the moment. I've asked Angel to confirm. :-)
