I was looking for data on how to drive the commodity compact-flash
devices actually. I already have a data sheet on how to flash one
of the Atmel chips directly, but then I need to either download to
a "real computer" for detailed analysis, or develop a "carrier" to
plug into the desktop. (In theory, I could drive it off a parallel
port, but that's not as "neat", nor do many Palmtops have those ports.)

If the CF devices are I2C, then that's no big deal.

Thanks for the pointer. I'm already on half a dozen mailing lists
delivering over 200 messages a day. Might sign up for a week to see
if I can keep up with traffic.
