[Coco] batch file processing

[Bob Devries]

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.

Regards, Bob Devries
