Are hardware upgrades for the Apple IIc still available?

[sbdocker@acs.ucalgary.ca (Sean Brendan Dockery)]

I have an original Apple //c and have decided that it might be a good
idea to upgrade the hardware to the newest motherboard if I can.

Are upgrades from Apple Computers, Inc. are still available?  If so,
is the upgrade free or must I buy a UniDisk to get one?  Or, would it
be better to go through a mail order company to get it?

If the former avenue of getting it from Apple is still available, how
should I get in touch with Apple?  Is there a specific email address
to which I can write?

Thanks in advance,

Sean

PS: I skimmed the FAQ, but I didn't see anything along the lines of
hardware upgrades.  If the answer is there, please direct me to it.
