No, it stays positive. Just a lot of ripple (between 2 and 5V).
Hopefully it's as simple as replacing the filter capacitor. The power
supply in this thing looks like it's going to be fun to pull out :).

The wiring for
the DIN socket is exactly as Tony describes, including
the 12V line. So that should be easy to wire up. On the negative side
That is
what I call a 'lucky guess' :-)
of things, the power supply's 5VDC line is
basically AC at the moment.
This wouldn't be so bad except that the seller powered the system up
before listing it, so I hope nothing got damaged...
Hmmm.. Does it acvtually go
-ve, or is it just exessive ripple (maybe
dropping to 0V every half cylce)? I would guess the latter, indicating
the smooting capacitor has totally dried up. This is unlikely to have
done much damage, although of course you will ahve to fix it befroe the
system has a chance of working.
