new find: an Intel MDS 800

I have a white MDS 800 System. It was sold in Germany by Siemens and they
relabelled it to SME 800 ("Siemens Microcomputer Entwicklungssystem").
It has an external 8"-double drive and a dumb terminal. Inside it is all
Intel. The only thing they changed internal: The glued "Siemens"-labels
over the original Intel-logos on the PCBs.

You can see it:

We are running ISIS-II inclusive KERMIT on it. One time Christian Corti
succeeded to boot a CP/M 2.?. But in the meantime this disk was damaged.
I found a very old CP/M source, dated "11/21/75" in the net, written in
PL/M and was able to translate it with the original PL/M-compiler
written in FORTRAN (dated: JAN 1975) on our SUN 4/260.
What is needed: To adapt the original BIOS for single density disks to
the double density drives on our system and to make bootable floppies.
