MonoFix by Thomas Binder. The ATARI Falcon030 can be connected to the SM124/144/146. It will then automatically display ST-high-res. But there is a little problem (at least with TOS 4.01): Some (older) programs quit saying they only work in high resolution, but the resolution definitely is "ST-high". And Maccel doesn't invert the screen periodically, as it is used to be in ST-high, it only inverts it once. This program fixes that bug.
