David Gesswein mfm_emu MFM Hard Disk Reader/Emulator electronics and the PS/2 keyboard protocolThis unit is intended to read MFM hard drives for archiving and to emulate one or two MFM hard drives to replace failing MFM drives. The image read from a real hard drive can be used for the emulation. In theory the unit can emulate any MFM hard drive. In practice there are enough variations in how controllers use the drives that software changes have been needed to make it work with some systems. You will need to use a command line to operate the
