I should know this, but I can't easily find the answer...
I have a BBC B+ with (1770)DFS (V2.x)( and ADFS (V3.5x) (or at least I
think those version numbers are right). It is cabled up to a single 80
cylinder double-sided disk drive.
I wish to read some files of a 40 cylinder (DFS) disk. I seem to remember
there was a command that would cause the drive to double-step, but only
allow reading. What is it?
