*Note: I looked at 9 laptop hard drives (6 Travel Stars by IBM, 2 Hitachi, and 1 Toshiba) and none of them matched as to what was master, slave or cable select, and all required some kind of jumper at the header to set this option up. Only on two drives was no jumpers made the drive as Master.

I am sorry, my previous image was askew.

But I did probe the six pins at that end of the WS/PDQ adapter to find that they are not connected to anything at all. My issue was not an incorrect jumper, it was no jumper.(but I use this adapter in my 1400 anyway, so no problem)

Silly apple, covering unused pins. You might presume a shorter connector would be cheaper.

Since the screw holes do not line up on my adapters, I use thick double sided tape, which also insulates the adapter from the metal caddy.

In my 286 I had doublesidednessly taped an adapter to a section of plastic from some packaging to bridge a gap in the metal right where the adapter needed to be. Seems to stay put.

Q: MacJunky - did you have to bend back or cut Pin #20 on your adapter because of the blocked pin on the connector? On the ones I have I had bend them back.

No, there is not even a pad for it on the PCB. I do however have other adapters that need some snippage.
RE: the other pins... it would be more reliable to just desolder them and either bridge pads with a wire or solder wires to a header glued on a clear area of the PCB.
