On the backside there is some unused slot with exactly the size of a
50pin Centronics connector and directly behind this there is a 50pin
internal SCSI connector with some kind of terminator plugged in.

Yup, read about this too but neve saw a 345 with fast HPIB only.

On the front side is another 50pin SCSI connector, a 4 pin power
connector and some kind of non standard rack to mount a HD into, the
only problem is that the holes aren't placed where today's HDs want
their screws.
