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.
