This sounds like the old Wavemate Bullet. If so, the hard disk
controller is connected through a 50 pin SASI/SCSI/bus-extender header
(J1) on the right hand side of the board. I have a couple of those boards
that were rejects and are not fully populated. That little sucker was
priced at $749 including CP/M 3 according to an old price list that I have.
Wavemate is no more, though.

: - on the MFM hard disk controller there is also a Z80 CPU (mostek). The
: controller board is placed beneath the mother board

Wavemate sold a HDC, also.

: Connecting an asynchronous terminal device to either of the DB25 connectors
: does not result in any text on the screen, only some strange characters

: the harddisk initialises (you can hear some head movements). There is no

: the bootfloppy and the OS?

I can't help you with a system disk for it, unfortunately. Wish I had
one for the archive!

: From the amount of memory one can expect it to be a CP/M 3 system. If so, I
: would like to revive this system, just for fun.

Yes, it was CP/M 3,see above.
