[Coco] Help with MacMAME (Tony Schountz)

Mon Mar 24 16:28:57 EDT 2025

Unfortunately, I really will only run this with OS-9 Level II. I have xroar
installed in /usr/local/bin and I can launch it using "xroar -machine
coco3", but I still cannot seem to attach the OS-9 level II boot disk
image, or whatever is causing the "?SN ERROR" message. It seems to me that
this means that "DOS" is not recognized by the emulated CoCo3.
