Had some spare time today, and decided to play with my Kodak NC 2000e (the "Associated Press camera"). I've used it before, and as far as I could remember, I didn't have any problems making it work.
Tried one PCMCIA memory card after another. None of them worked. Tried a few CF cards in a PCMCIA adapter. Didn't work. Read my own DCS420 article, and realized there was one more card I hadn't tried. I went looking, and finally found it in a Nikon E2.
For future reference, here are the cards that did NOT work:
Nikon EC-15 (15MB)
Fujifilm HG-10 (10MB)
Smart Modular Technologies (?) ATA PC Card (130MB, IIRC)
And the one that DID WORK:
IBM Solid State File (40MB)
Dated May 1995
I'm not 100% sure, but I think this is the only card that's working with all the cameras I've tested. The card originally came with my E2N. The IBM card is the one that's labeled IBM (!):
