Hi and thanks for all the help I got! Both on the list and via email 

A couple of days ago I did a quick test of the drive and I was able to  
load tapes, both manually and with automatic tape loading. It's a really 
nice drive. BPI were detected automatically so the drive seems to be i 
good condition.

I haven't been to my storage yet since I saw the new documents scanned 
by Al, but from the pictures I have taken it looks like it is a 
SCSI-drive, the other interfaces uses two cables instead of one.
Whenever I get some time to spare I will try to get the drive connected 
to a linux computer. It is possible to run the 2920 both as singel ended 
and differential so I should have a lot of different interface cards to 
choose from for the PC end. It looks bright right now. :-)

The reason I haven't responded before is that I got busy with a rescue 
of a NORD-1 computer in southern Norway. It took 28 hours to fly down to 
Göteborg to meet up with a friend already in the south, drive to Norway, 
load the computer in my friends van and drive it back to Umeå. I hope my 
reason for the lack of interest in this thread is excusable. :-)
The computer is the first model made by Norsk Data AS, it has serial 
number 47 and was built in the summer of 1972, equipped with 32 kword of 
core memory. It's one of my dream machines and it is almost complete. :-D
