I have the Sony Slimline ( desktop/laptop ) unit. It came with one PC slot. I bought a Kanguru burner that came with their special cable ( $49 ) a foot long. One end has a 36 pin connector and the other is a pcmia card. I can't get my burner to initialize the plug and play routine, as I had to reinstall windows 98. At first, the tech told me that its my cable...its no good. I borrowed a friends laptop and tried it there, and Voila, it works beautifully...so much for a defected $49 cable or burner. My ? is how does one know if my pc slot is defective? I don't have any other product with a pcmia card to try it out.
