I have a FloppyEMU that works with the 2/5. I own two, a Model A setup for the 2/5 and a Model B setup for the 2/10.
The current Floppy EMU software has issues with the 2/5, you must use the older firmware. Problem is that I don't know if the older firmware will work on the Model C. I have a hunch that the older firmware is not compatible with the new display on the model C.
From the BMOW website:
Macintosh and Lisa firmware, for all Floppy Emu models: hd20-0.8E-F14
Lisa 2/5 compatibility firmware, for Floppy Emu Model B or A: lisa-emu-1.0S7-F11
You will have to email Steve at BMOW and ask him.
I don't know for sure but I think LisaCompose for driving a typesetting system, I don't think it will do you much good without the typesetting hardware that goes with it.
