Request for V41 Emulator

Have you tried SwissMicros' DM42 Programming tool?

This is intended (clearly) for the DM42, however the 42S dialect of FOCAL is pretty close to the 41's original dialect, and it's possible it will work for you. Since you can simply paste the text source in, it's easy to give it try, so probably worth checking out.
