How long since you last used it?
Not totally sure, but around a year.

take it from this that you don't get the BASIC message?
Indeed you don't. However, by pressing Ctrl-F BREAK, you can get a *
prompt, and then typing BASIC and hitting Return will drop you into
BASIC.
The only testing I did after that was a simple 10 PRINT "HELLO", 20
GOTO 10, RUN. It worked.
Being a Master, it's quite likrly the
internal battery is flat and the
configuration RAM is corrupted. There's a key combination to reset this
(I forget it, it's in the mnual, though). Try that, and then configure
the options you want. If that cures it, replace the batteries...
From the reading up I was doing earlier this
evening, it's switching
on whilst holding down R.
That sounds right. Assumeing all this works, it's very liekly the battery
has gone flat. AFAIK it's 3 AA-size primary cells (non-rechargeable) in
series. Officieally you were supposed to replace the whole assembly with
the Acorn spare, but I have no idea why (other than Acorn could then sell
you a spare). I just repalce the cells and have had no problems.
