Does anyone have an Apple ][ with the DuoDisk drive? I recently found one but the controller card is missing the connector. A clear picture of the interconnect cable that goes bewteen the card and the connector that bolts onto the back of the case would give me all the information I need to replace it.

Is it a straightforward pin-for-pin arrangement or are lines swapped around before they reach the DB-19 connector?

Thanks! Those were actually pretty helpful. It looks like the ribbon cable is attached to the header connector in a fairly straightforward manner.

Fixed! it is almost straightforward except for that pin 19 on the card is NC and and pin 20 (on the card) goes to pin 10 on the connector. With the rest of the pins it's a staggered arrangement used in crimp connectors(i.e. pin 1 goes to connector pin 1 while pin 2 goes to connector 11, pin 3 to connector pin 2 then pin 4 to pin 12 and so on).
