The boot track in the image file is at logical track 68 as seen by
the DOS command so a simple "DOS" fails to see it. However, you can
get around this by telling DISK BASIC to boot from track 68 instead!
Try to boot it this way:
This should at least start the boot sequence. I seem to recall that
MESS handles a DSDD image if it has a '.OS9' extension name??
(I don't use MESS myself so please correct me as needed. Maybe just
renaming the extension is sufficient??)
For the JV/JC emulators you must patch the DD.FMT byte in LSN0
to trick the emulator into treating it as a single-sided image.
