I have found on FISH PD three demo versions of GRAFFITI editor written probably in AMOS like splash screen says.
It is very good, >>> fff-531, ff-610, ff-620.
Something like Deluxe Paint 4, graphic editor.
But all versions do not save or load anything from disk. If someone knows anything where I can find it, please let me know.
