I am sure I can get it out, but will I get it in again? Maybe taking
it apart completely isn't necessary.

There are two controllers (at least): One has DILOG on the blue 
plastic thing with which you can take it out. This is similar to the
brown plastic handle on DEC cards (like the M7555, which I just
learned is the RQDX3 controller).
This is a SCSI controller with 50 pins connector. I took it out. It
has a NCR 53C90A on it. This only has an Exabye tape connected to
it. Machine will not get through NetBSD boot without it. Hangs at 

uba0 at ibus0: Q 22.

Do I have to tell the machine in the boot monitor that it isn't
there?

The hard disks look like ESDI to me with their usual two connectors.
The controller (number 2) which they connect to is not DEC. It says
DILOG as well on the card. I haven't taken this out yet.

The funny thing is that there is another card that seems to be a disk
controller (number 3). This has no name on it (as far as I can see),
but it does have the brown plastic handles. It connects to the M7555.
In fact it is the only thing connected to the M7555. The card itself
is connected with a cable ("Spitfire-Strip") that goes inside
somewhere and that connects probably to the floppy drives. Thus:

M7555 --- Unknown controller --- Floppy drives

I suppose this is "uba0 at ibus0: Q 22". There are 4 unused connectors
on it. Would it be that the (or some) harddisks can also be connected
to this???
