With the help of Roger Ivie I have now bootblocks/boot which talk to
the DZ-chip directly to produce output to the serial console and use
VMB-routines to read from boot-device (ie. floppy).
But in order to make edlabel/copy write to the disk, it seems that a 
real driver for the disk/floppy/tape controller is neccessary.

Having working I/O-routines makes debugging much easier. :-)

PS: Anybody having machine-readable documention on the VS2000's
    disk/floppy/tape controller?
    Anybody (preferred Germany/Europe) having a technical manual
    for VS2000 which I could borrow for some weeks?
