[Coco] Nitros9 L3

[L. Curtis Boyle]

I am going from faint memory here, and hopefully can verify or correct me, but I think we were doing the error trapping experiment on the TC-9, because the ROM vector at $FF00 was a better fit/of more use their then on the Coco 3.  Does this ring any bells, Bill?
