A late reply to this thread, sorry about that.

I have had some progress in this matter:
Good news, any other progress since June?
I have the cab kit for it. It has a DB25 connector as
well as a 50 pin male
IDC connector. But there is also pads for a 10 pin connector that seems to
be for the second serial port. What is the use for this second serial port?
The board has a Signetics SCN2681 DUART chip so it definitely has two
serial ports.
I'm missing the CAB kit for my boards, they only have a 50 pin connector
at the edge of the board. Can that be plugged in to a 50 pin SCSI disk
right away? Or do I need to make some modifications or find a CAB kit?
Zane, Pontus: What is your version?
Ok, So I've finally dug my boards out. I found three of them!
1. VIK/QDT, PAL: VIK-DT, ROM: Q/B A3.7
2. VIK/QTO, PAL: VIK-TO, ROM: Missing sticker :(
3. Missing Sticker, PAL: VIK-DT: ROM: Q/B A4.3
Just to verify, QDT is Disk and Tape, QTO is Tape Only and QDO would be
Disk Only?
And if the PAL note is any indication #3 in the list might be a QDT?
I also found some other interesting cards, two Viking UTO, which I
interpret as Unibus Tape Only. Would these be possible to convert to
accept disk?
In another box was a CMD CDU-720/T. A Unibus scsi tape controller, same
question here, can you coax it to talk to disks?
Mattis: If you want you can borrow and dump the 4.3 ROM if you like.
