emulatorII-list

Hi all, does anyone know for sure if the HD units had different binary information in their EPROMS (scanner and main)?
I am still trying to figure out this downgrade that I need to finish.
Like I said before, with the HD hardware removed it will no longer boot.
The floppy engages and the display shows the O.S. and that is it.
If I get a new set of EPROMS will that do it?
