Superdrive interface?

[John Le Febvre <john@klatch.demon.co.uk>]

Can anyone enlighten me as to what a Superdrive interface looks like?

I picked up a FDHD drive at the weekend for an enhanced //e, and have
been offered an interface card which the present owner thinks MIGHT be
the right one.  He says it has 2 x 15 pin D-sockets on the card.  I
know the FDHD drive has a 15-pin interface, but it's daisy-chainable,
so why the extra socket on the card?

If it's not the right interface, I can get some more info on it when it
arrives in a day or two.

Thanks in advance,
