[Coco] batch file processing

I just located the disk image you mentioned.
I booted it using FCC. It boots into a VDG type screen. Black border, green
background and black characters, 32 x 16 size.
This was the default screen for an unmodified copy of OS-9 Level 2.
Why you're getting all black is a mystery to me.
