I have an fully working 8280.
In total  have 5 TM848-2 drives (two in the 8280). One has a headcrash. One
was OK and I repaired the other three (TTLs failed: f.ex. 7474).
My drives have three different PCB revision - with different jumpers.
At all drives are M1 and M3 closed.
In the web are different installation manuals/service manuals for the
revisions.

On my site is a picture of the controller-board with the most common
revision:
