Yes, and by issuing *TIME or PRINT TIME$ after powering off for a few
minutes to see if the date and time are retained.  usually, when the
CMOS battery is on its way out, the time is the first thing to go.

Ok (see later)

0.  As it's an 80-track drive, it's probably double-sided, so in DFS the
other side is drive 2.

Check the data cable has not been pulled off the back of the drive.
Check for bent pins on the connector.
Check that DFS is *INSERTed and the default filesystem (*config file 9).
Check the "Acorn DFS" banner appears on boot.

Yes.

*configure lang 12
*configure file 9
*configure noboot
*configure nodir
*configure fdrive 5
*configure nomount

followed by a ctrl-break, should get you going.  Also check that *ROMS
does not show any ROMs as "unplugged" - in which case, *INSERT them.
