Yes.  The Z-RAM board was known as "CP/Maker" in Europe and Vector was one of 
the distributors.  I found a couple of advertisements and put them on this page:

Z-RAM disks can be identified by looking for a large REL file in the CBM DOS 
directory.  It contains an image of the CP/M filesystem.

SoftBox disks store the CP/M filesystem directly in CBM DOS sectors.  These 
disks may have two CBM DOS files in the directory, "K" and "CP/M", or may have 
no CBM DOS files.  The directory will show most blocks as free when in fact 
the sectors are full of CP/M data.

I'd like to look at these image files.  Could you please send them to me?
