I bought a JMK PCMCIA IDE card a while ago, but I can't find product details or manufacturer website.

Does anyone know the pinout for this 44 pin IDE interface?
Since it has all 44 pins, I am not sure which one is pin 1.

Thanks.

Well it's a 44 pin connector with no key that looks like it's meant for a 44-pin 2-mm pitch cable to plug into. Some of the extra pins provide power so a 40-pin cable won't work with it, but it should be able to power a laptop hard drive?

The 5v pins are the quickest way to test with a multimeter in ohms / beep mode - they're in the same place on the top and bottom row.

The attachment pinout-check.jpg is no longer available

Check whether the pins in green or the pins in red are connected together and that's pin 41/42, so pin 1 is at the opposing end and it should probably be marked for future reference

Thanks! I just checked and the red pins are connected together.

P.S. I forgot 2.5" IDE has 44 pin instead of 40 pin, I updated my original post.
