My digital camera uses SmartMedia, but my TRGNet PalmPilot clone
uses CF pluggin accessories. Both media face similar problems.
For laptops, PCMCIA adapters are definitely the way to go. They're
fast and look to the system like little pluggin IDE hard drives. Both
media have these adapters. I use my laptop for accessing this media most
of the time. There are adapters available to install PCMCIA slots in
workstations. This isn't a bad idea if you are working with SmartCards
and other media adapters like these. A CF to PCMCIA adapter is about
$18 (Best Buy). The PCMCIA to ISA/PCI is going to run you more, but I've
seen some single slot adapters that weren't too bad.
The Floppy adapters require special drivers and I haven't heard of
anyone to get them to work under Linux (doesn't mean there isn't anyone,
or maybe no one has tried). Problem is that the geometry of the "media"
under the floppy doesn't agree with anything the kernel knows anything
about. I think these are only for SmartMedia (CF is too thick) and you
didn't mention them. I mentioning them only for completeness.
I have no experience with the parallel port adapters, what so ever,
and have no intention of aquiring any experience.
As far as USB goes. I have one of the Lexar Jump Shot USB adapters
for USB enabled CF cards (doesn't work with CF cards which are NOT USB
enabled). Support for these adapters is not yet in place. Lexar says
it's being worked on and will be on their web site as soon as it's available.
The USB developers are saying that they are talking with some CF manufactures
but won't say who (gee... What a coincidence) but do say that they will have
support for some adapters shortly. The USB subsystem recognizes the CF
card, there just isn't any appropriate driver for it yet.
