Hi,
Perhaps, the following info could be useful for the usage of the HxC floppy drive emulator with the Linn9000:
There is a project called "linn9000fs" which enables access to the Linn9000 floppy filesystem which is contained within IMG-files.
IMG-files can be created from hfe-files with the help of "HxCFloppyEmulator".
The open-source project "linn9000fs" can be found here: https://sourceforge.net/projects/linn9000fs/
There is a command-line version called "l9000fs", and an (older) version with GUI called "gui9000fs".
For further information please see the README-files within the distributions.
Hope this is helpful.
Regards,
kmi9000
