[Coco] SCD-DOS for Dragon computers

[Zippster]

So if I cut the first ‘x’ bytes off to get the file size down to 184332 bytes,
would SCD-DOS handle that, or would the mangled header cause problems?

Or I guess just cutting out bytes 13 to (file size - 184320) would be the
way to go.

Not sure what header info the SDC firmware uses.
