Problem with installing Iomega ZIP100 Drive in 2KXL

Sorry for confusing you.

I hope the following text will help you to understand:
The original 2 wire 5V cable you saw on the picture is from my SE2.
I want to put the ZIP drive in the SE2.

Then i have a SE3 with a working card reader. The 4 wire cable you saw on the picture came with the card reader and it is fixed with some glue at the card reader end, so i can't test the 4 wire cable from the card reader with the ZIP drive.

That's the reason why i've put the whole card reader into my SE2, to get sure that the Connector of the MPC Mainboard is not broken, and it worked. And it worked even in my SE3 because the card reader was installed in it before i tested it in the SE2.

Summary:
-Card Reader worked in both MPC's, so the Mainboard is not broken
-ZIP drive worked not, neither in the SE2 nor in the SE3

So i guess that i really need a 4 wire cable to make it work, that's the reason why i ordered one yesterday.
The last option is, that the ZIP drive is broken, but i have the opportunity to test it as recently as the 4 wire cable arrives.

Hope it helped you to understand.

Okay, now it works.
I connected all 4 pins of the wire. Although the MPC boots very low, but the main thing is that i can load samples etc...

Thanks @ all for the help!
