Thanks for the reply,
As I am only in the posession of a laptop, PCI is not an option.
Are there any PCMCIA otions out there, or should I wait until Firewire/USB 2.0
becomes more available?
I seem to remeber seeing something like a PCMCIA/CF card that might work...but
only for 2 channel...
Thanks again,
Wade
