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

[Dittel, Torsten]

BTW, Artefact Colors are "rediscovered" on other machines as well, see corresponding section in

It looks like other gear's emulators spend effort in correctly emulating NTSC artefacts, i.e.

Additionally, see http://atariage.com/forums/blog/105/entry-6693-color-computer-3-artifact-art/


I think the "greyscale" NTSC artefacting has not yet been implemented in any of the CoCo3 emulators, only the well known "red-blue" from CoCo1/2's PMODE4 (for both SCREEN1,0 and SCREEN1,1, at least in Xroar with corresponding emulator settings).


In that context I want to mention the "PAL artefact colors" on composite output which combine colors in horizontally alternating lines instead of vertical in NTSC which have neither been emulated yet until now.
