This are the emu files I had saved from my backups.

I used a backup for /etc and /root  with tar.

I don't know which emu file is bootable as I have no DM-V anymore but if you 
make translation files and the 1st sectors are not '00' 'FF' 'E5' there may 
be a bootable system on the emu file.

For MSDOS I used 20MB harddisk and you have to use a special format  programm.
Use FMT20.COM which is in 5DOS211.TD0 or similiar.

With CP/M 2 and CP/M 86 the 20MB HD is not usefull, even you can write to it.
The directory isn't made for 20MB so you may overwrite some entry's and got
lost dir entry's  and a bad filesystem.
So please don't try 20MB with CP/M and use a 10MB  emulation for save.
