I know that a PCI bus cannot be mixed with a PCMCIA bus at all. I also know that NI does not sell or provide any PCI to PCMCIA converter or viceversa for performing the operation that you want to do. However, I have heard that some people have gotten those PCI to PCMCIA converters or viceversa, but don't know what company from. Sorry about that! You should do a little bit of more research. Nevertheless, I know for sure, that NI will not be liable for the performance of the PCI daq board with such a device. It will be up to you.
Finally, my suggestion would be to use a PCMCIA daq board for your laptop, rather than getting an additional device. However, if you find the device, and find out that it is reliable, go for it.
Hope this info helps,
