If you need to upload software into an MFX keyboard, the only method 
I'm aware of is from an MFX mainframe. Quit the system, and type 
mfxload (return) The keyboard needs to be "waiting" for code, (I can't 
remember which way round these two steps are). When code is being 
transferred across, there will be a visual indication of the keyboard 
filling up in the LCD screen, and at the end of the process, the 
mainframe OS9 # prompt should re-appear. The MFX keyboard may even auto-
boot.

Hope this is helpful, regards,
