I know a few of you took the time to integrate the compact flash socket into your system board, and it strikes me that these two devices might be a welcome addition to those systems.
Whilst surfing my favorite PDA site, I came across the Sycard compact flash to pc card extender, which will work with various network and other PCMCIA devices.
Also of interest was the "CF Pocket" Compact Flash Type I to Type II Adapter which may allow you to use an IBM Microdrive with the Iopener, if you'd prefer not to use a standard laptop drive, or want something small enough to take it with you.
