[Coco] Need help identifying author of an OS-9 program

[Robert Gault]

It looks like Torsten is correct. Artifact colors are emulated on PMODE screens by MESS and VCC but 
not on the HSCREENs.
With both MESS and VCC, the .vef pictures are many levels of gray when set for CMP and red and green 
colors when set to RGB. With a real Coco3 and a composite monitor, these .vef pictures really look 
excellent.
