For Mech's card reader you need to enable LUNs on the 3000 or use a PCMCIA adapter for the CF card.
I didn't enable LUNs on mine when I first got it, but I could only use the PCMCIA card slot with a CF adapter.
After I got the battery repaired, LUNs were enable and it's works great. I am able to use all the slots.
If you want to run Shapeshifter or Fusion, you can put an SD card in the SD Card slot and use it as the MacHD.
Here is a shot of what she looks like right now. I am trying to figure out a place to put the card reader. I may have to come up with some stand offs or something.
