Hi,

I have an old Compaq 486 (without a hard drive) I wanted to use an IDE-CF adapter but I have a problem with the power cable of the computer :

What kind of "molex" is that ? Is there an adapter I could use ?

I found this very old (and very expensive !) hdd on ebay that has a female port for this weird connector : http://www.ebay.com/itm/IBM-171MB-IDE-P-ATA-3 … 7wAAOSwcu5URoJ2

Anyone knows the name of this type of connector ?

pin 1 is ground, pin 2 is +12v and pin 3 is +5v

I have 2x 270mb ide drives out of old apples that have this connector.

Never actually seen it used though. I'll get some pics up later if you want. For the record, my drive is a Quantum ProDrive LPS.

It is a mistake to think you can solve any major problems just with potatoes.

That's a Berg connector, commonly used on floppy drives. Molex to Berg adapters can be found. They're becoming more common than hardwired Berg connectors on modern PSUs. Ask around in case anyone's throwing them away.

He is actually referring to the 3-pin connector. it is NOT the same as a typical 3-pin connector you are used to. the pin itself is blade shaped, not square.

I noticed the 3pin connectors on some old hard drives but never knew what they are meant for. Thanks!

personally I would cut off a new floppy power connector, GENTLY insert the wires into the existing 3-pin connector (DOUBLE CHECK VOLTAGES) and hot glue it in place.

I NEVER will do a permanent modification if I can avoid it.

I mustn't have been looking straight and somehow thought that plug was only in place of the Bergs. I see that we have no 4 pos Molex plugs to work with at all.

Found this on TULARC:

The mating connector for the 3-pin connector is Molex series 54-84
(header), Molex part number 39-01-033 (housing), and terminal part
number 39-00-0031 (loose) or 39-00-0023 (strip).
