[Coco] batch file processing

[Wayne Campbell]

Thanks for doing that, Bob. It helps me know that something else must be 
different, but I don't know what it is. I know that the os9l2_1.os9 image 
boots perfectly, with green background and border, black text and a magenta 
cursor. OS9SYSMR.os9 boots, but shows me a black screen. Updating to the 
newer version of MESS did not change it.
